Using the regular gitcommit highlighter would not make sense, as it is
intended for the message templates seen when making a commit. Whereas
format-patch .patch files have the headers as email headers.

You can load the mail header highlighting on top of diff highlighting
like this (which only triggers for patches that look like emails):

  au FileType diff
    \ if getline(1) =~ '^From ' |
    \   unlet b:current_syntax |
    \   runtime! syntax/mail.vim |
    \ endif

But maybe there is something else that you wanted to highlight. It's not
clear to me what you want from gitcommit's highlighting. Is it the
"complain about long lines" highlighting? I think that you'd have to
pull out of the gitcommit.vim and execute manually (and you'd have to
tweak the regex to take into account the "Subject: [PATCH] bits).
