Subject: runtime(help): Unset `'comments'` and `'cms'` options
X-Git-Tag: v9.1.1603~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=adfea9b4e68f39744fcb6ce7840e1c3c3b4637db;p=thirdparty%2Fvim.git

runtime(help): Unset `'comments'` and `'cms'` options

Problem:  Vim's help file doesn't have any syntax for comments, but
          'comments' and 'commentstring' are still set in the help
          buffer.
Solution: Unset 'comments' and 'cms' in help buffer

closes: #17889
