Complement "g:java_ignore_javadoc" with "g:java_ignore_html"
and "g:java_ignore_markdown" to allow selectively disabling
the recognition of HTML and CommonMark respectively.
(Note that this is not a preview feature.)
======================== LIMITATION ========================
According to the syntactical details of JEP 467:
> Any leading whitespace and the three initial / characters
> are removed from each line.
>
> The lines are shifted left, by removing leading whitespace
> characters, until the non-blank line with the least
> leading whitespace has no remaining leading whitespace.
>
> Additional leading whitespace and any trailing whitespace
> in each line is preserved, because it may be significant.
the following example:
------------------------------------------------------------
/// A summary sentence.
/// A list:
/// - Item A.
/// - Item B.
///
/// Some code span, starting here `
/// 1 + 2 ` and ending at the previous \`.
------------------------------------------------------------
should be interpreted as if it were written thus:
------------------------------------------------------------
///A summary sentence.
/// A list:
/// - Item A.
/// - Item B.
///
/// Some code span, starting here `
/// 1 + 2 ` and ending at the previous \`.
------------------------------------------------------------
Since automatic line rewriting will not be pursued, parts of
such comments having significant whitespace may be ‘wrongly’
highlighted. For convenience, a &fex function is defined to
‘correct’ it: g:javaformat#RemoveCommonMarkdownWhitespace()
(:help ft-java-plugin).
