Problem: - Help tags provide a good way to navigate the Vim documentation, but many help documents don't use them effectively. I think one of the reasons is that help writers have to look up help tags manually with `:help` command, which is not very convenient. - 'iskeyword' is only set for help buffers opened by `:help` command. That means if I'm editing a help file, I cannot jump to tag in same file using `Ctrl-]` unless I manually set it, which is annoying. Solution: - Add omni completion for Vim help tags. - Set 'iskeyword' for `ft-help` closes: #17073 Co-authored-by: Christian Brabandt <cb@256bit.org> Signed-off-by: Phạm Bình An <phambinhanctb2004@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
