Format a line of one or more IPA pronunciations as {{tl|IPA}} would do it, i.e. with a preceding {"IPA:"} followed by
the word {"key"} linking to an Appendix page describing the language's phonology, and with an added category
{{cd|<var>lang</var> terms with IPA pronunciation}}. Other than the extra preceding text and category, this is identical
to {format_IPA_multiple()}, and the considerations described there in the documentation apply here as well. There is a
single parameter `data`, an object with the following fields:
* `lang`: Object representing the language of the pronunciations, which is used when adding cleanup categories for
   pronunciations with invalid phonemes; for determining how many syllables the pronunciations have in them, in order to
   add a category such as [[:Category:Italian 2-syllable words]] (for certain languages only); for adding a category
   {{cd|<var>lang</var> terms with IPA pronunciation}}; and for determining the proper sort keys for categories. Unlike
   for {format_IPA_multiple()}, `lang` may not be {nil}.
* `items`: List of pronunciations, in exactly the same format as for {format_IPA_multiple()}.
* `err`: If not {nil}, a string containing an error message to use in place of the link to the language's phonology.
* `separator`: The default separator to use when separating formatted items. Defaults to {", "}. Does not apply to the
  first item, where the default separator is always the empty string. Overridden by the per-item `separator` field in
  `items`.
* `sort_key`: Explicit sort key used for categories.
* `no_count`: Suppress adding a {#-syllable words} category such as [[:Category:Italian 2-syllable words]]. Note that
  only certain languages add such categories to begin with, because it depends on knowing how to count syllables in a
  given language, which depends on the phonology of the language. Also, this does not suppress the addition of cleanup
  or other categories. If you need them suppressed, use `split_output` to return the categories separately and ignore
  them.
* `split_output`: If not given, the return value is a concatenation of the formatted pronunciation and formatted
  categories. Otherwise, two values are returned: the formatted pronunciation and the categories. If `split_output` is
  the value {"raw"}, the categories are returned in list form, where the list elements are a combination of category
  strings and category objects of the form suitable for passing to {format_categories()} in [[Module:utilities]]. If
  `split_output` is any other value besides {nil}, the categories are returned as a pre-formatted concatenated string.
* `include_langname`: If specified, prefix the result with the language name, followed by a colon.
* `q`: {nil} or a list of left qualifiers (as in {{tl|q}}) to display at the beginning, before the formatted
  pronunciations and preceding {"IPA:"}.
* `qq`: {nil} or a list of right qualifiers to display after all formatted pronunciations.
* `a`: {nil} or a list of left accent qualifiers (as in {{tl|a}}) to display at the beginning, before the formatted
  pronunciations and preceding {"IPA:"}.
* `aa`: {nil} or a list of right accent qualifiers to display after all formatted pronunciations.

Format a line of one or more bare IPA pronunciations (i.e. without any preceding {"IPA:"} and without adding to a
category {{cd|<var>lang</var> terms with IPA pronunciation}}). Individual pronunciations are formatted using
{format_IPA()} and are combined with separators, qualifiers, pre-text, post-text, etc. to form a line of pronunciations.
Parameters accepted are:
* `lang` is an object representing the language of the pronunciations, which is used when adding cleanup categories for
   pronunciations with invalid phonemes; for determining how many syllables the pronunciations have in them, in order to
   add a category such as [[:Category:Italian 2-syllable words]] (for certain languages only); and for computing the
   proper sort keys for categories. `lang` may be {nil}.
* `items` is a list of pronunciations, each of which is an object with the following properties:
** `pron`: the pronunciation, in the same format as is accepted by {format_IPA()}, i.e. it should be either phonemic
     (surrounded by {/.../}), phonetic (surrounded by {[...]}), orthographic (surrounded by {⟨...⟩}) or a rhyme
	 (beginning with a hyphen);
** `pretext`: text to display directly before the formatted pronunciation, inside of any qualifiers or accent
     qualifiers;
** `posttext`: text to display directly after the formatted pronunciation, inside of any qualifiers or accent
     qualifiers;
** `q` or `qualifiers`: {nil} or a list of left qualifiers (as in {{tl|q}}) to display before the formatted
     pronunciation; note that `qualifiers` is deprecated;
** `qq`: {nil} or a list of right qualifiers to display after the formatted pronunciation;
** `a`: {nil} or a list of left accent qualifiers (as in {{tl|a}}) to display before the formatted pronunciation;
** `aa`: {nil} or a list of right accent qualifiers to after before the formatted pronunciation;
** `refs`: {nil} or a list of references or reference specs to add after the pronunciation and any posttext and
     qualifiers; the value of a list item is either a string containing the reference text (typically a call to a
	 citation template such as {{tl|cite-book}}, or a template wrapping such a call), or an object with fields `text`
	 (the reference text), `name` (the name of the reference, as in {{cd|<nowiki><ref name="foo">...</ref></nowiki>}}
	 or {{cd|<nowiki><ref name="foo" /></nowiki>}}) and/or `group` (the group of the reference, as in
	 {{cd|<nowiki><ref name="foo" group="bar">...</ref></nowiki>}} or
	 {{cd|<nowiki><ref name="foo" group="bar"/></nowiki>}}); this uses a parser function to format the reference
	 appropriately and insert a footnote number that hyperlinks to the actual reference, located in the
	 {{cd|<nowiki><references /></nowiki>}} section;
** `gloss`: {nil} or a gloss (definition) for this item, if different definitions have different pronunciations;
** `pos`: {nil} or a part of speech for this item, if different parts of speech have different pronunciations;
** `separator`: the separator text to insert directly before the formatted pronunciation and all qualifiers, accent
   qualifiers and pre-text; defaults to the outer `separator` parameter.
* `separator`: The default separator to use when separating formatted items. Defaults to {", "}. Does not apply to the
  first item, where the default separator is always the empty string. Overridden by the per-item `separator` field in
  `items`.
* `no_count`: Suppress adding a {#-syllable words} category such as [[:Category:Italian 2-syllable words]]. Note that
  only certain languages add such categories to begin with, because it depends on knowing how to count syllables in a
  given language, which depends on the phonology of the language. Also, this does not suppress the addition of cleanup
  categories. If you need them suppressed, use `split_output` to return the categories separately and ignore them.
* `split_output`: If not given, the return value is a concatenation of the formatted pronunciation and formatted
  categories. Otherwise, two values are returned: the formatted pronunciation and the categories. If `split_output` is
  the value {"raw"}, the categories are returned in list form, where the list elements are a combination of category
  strings and category objects of the form suitable for passing to {format_categories()} in [[Module:utilities]]. If
  `split_output` is any other value besides {nil}, the categories are returned as a pre-formatted concatenated string.

categories to those lists. A single value is returned, the pronunciation, which is usually the same as passed in, but

Format an IPA pronunciation. This wraps the pronunciation in appropriate CSS classes and adds cleanup categories and
error messages as needed. The pronunciation `pron` should be either phonemic (surrounded by {/.../}), phonetic
(surrounded by {[...]}), orthographic (surrounded by {⟨...⟩}), a rhyme (beginning with a hyphen) or a combined
phonemic/phonetic spec (of the form {/.../ [...]}). `lang` indicates the language of the pronunciation and can be {nil}.
If not {nil}, and the specified language has data in [[Module:IPA/data]] indicating the allowed phonemes, then the page
will be added to a cleanup category and an error message displayed next to the outputted pronunciation. Note that {lang}
also determines sort key processing in the added cleanup categories. If `split_output` is not given, the return value is
a concatenation of the formatted pronunciation, error messages and formatted cleanup categories. Otherwise, three values
are returned: the formatted pronunciation, the cleanup categories and the concatenated error messages. If `split_output`
is the value {"raw"}, the cleanup categories are returned in list form, where the list elements are a combination of
category strings and category objects of the form suitable for passing to {format_categories()} in [[Module:utilities]].
If `split_output` is any other value besides {nil}, the cleanup categories are returned as a pre-formatted concatenated
string.
