runtime(java): Recognise the {@snippet} documentation tag (#14271) Commit: https://github.com/vim/vim/commit/3e72bf10a0a2fc34f01ff9663ed3324c2a140228 Author: Aliaksei Budavei <32549825+zzzyxwvut@users.noreply.github.com> Date: Fri Mar 22 21:32:48 2024 +0300 runtime(java): Recognise the {@snippet} documentation tag (https://github.com/vim/vim/issues/14271) Remember that ?code fragments are typically Java source code, but they may also be fragments of properties files, source code in other languages, or plain text.? Therefore, with these changes, markup tags are highlighted in the Java source files (as external snippets) and in the {@snippet} tags. Also: - Improve matching of the multi-line {@code} documentation tag with any contained balanced braces. - Recognise the {@literal} documentation tag. - Highlight stray blanks in comments. Related to an enhancement proposal for PCRE-like callouts discussed at https://github.com/vim/vim/issues/11217.
