Or in my case, /usr/local/libdata/vim/vim73/syntax/mail.vim
Since this file is on a shell account, and not my own machine (and not part
of my user account on the shell box), I can't write to it. (The mutt
& slrn I'm using, and the vim I'm using to initiate, edit & respond to mail
& news messages, are also on the same shell account.)
So I simply put
hi mailSubject ctermfg=MyChosenColor
in my .vimrc, and this seems to have worked. I did have to see this line
> hi def link mailSubject LineNR
in the syntax file to know to set "mailSubject" in .vimrc. Thanks for both
responses.
