This might not be very elegant but it should work (once tailored to your needs,
of course):
" Add this to your .vimrc file.
hi def link MyWord TODO
function! s:commentword()
syn clear MyWord
redir => groups
silent hi
redir END
let groupnames = map(split(groups, '[\n]'), 'matchstr(v:val, "^\\S\\+")')
for g in groupnames
if g =~ 'Comment'
exe 'syn match MyWord /WORD/ contained containedin=' . g
endif
endfor
endfunction
augroup CommentGroup
au!
au Syntax * call s:commentword()
augroup END
" End of code.
It relies on the fact the highlight groups for comment generally
contain “Comment” in their names. We could be even smarter and check
for each group whether it is ultimately linked to the Comment group,
but then opening a new file is noticeably slower.
Best,
Paul
