Re: Bug#1019257: vim: syntax highlight: roff, man: man highlighting could be improved with some roff rules

[Nate Bargmann]

I don't know if the following is useful for the bug report so I am
simply replying here as I found the described behavior annoying as well.

At the time I grabbed the most recent version of nroff.vim syntax file I
could fine which I see is dated 2021 Mar 28.  I placed it in
$HOME/.vim/syntax/nroff.vim

I see it checks for two variables both of which I enabled in my
$HOME/.vim/vimrc:

" Force extended highlighting for groff files.
let b:nroff_is_groff = 1

" Display nroff space errors
let nroff_space_errors = 1

I do edit some locally generated roff and MM files along with the
occasional man file.  The result is generally pleasing and consistent to
me.
