syntax/vim.vim question -- should vim's heredocs be highlighted with comment support?

[Charles Campbell]

Hello,

Its been brought to my attention (thanks, Naruhiko Nishino) that vim's
heredoc's syntax highlighting may not need to support commenting, either
old-style or vim9 style. Some of the examples show vimL use, where
comment support is nice, but other examples are just plain text. I'm
leaning towards removing the comment highlighting support inside vim's
heredoc syntax highlighting. Comments?

Yes, I'd remove it. It implies that those lines might not be included
in the list.
