[RFC/PATCH] remove vim syntax highlighting in favor of upstream

[Jeff King <peff@peff.net>]

[Tim Pope cc'd as the author of the official version. Tim: just an FYI,
but if you have any comments, please feel free to share]

[Shawn cc'd as the interim maintainer. I, for one, welcome our
new Java-programming overlords].

Here is a patch, then. Shawn, we should probably give any vim users a
few days to object in case there is something they don't like about the
upstream version, but other than that, I think this should be applied to
master.

remove vim syntax highlighting in favor of upstream

As of version 7.2, vim ships with its own syntax
highlighting for git commit messages, which is:

  1. more comprehensive in splitting up the various
     components of the file

  2. in accordance with the usual vim behavior for syntax
     highlighting (e.g., respecting b:current_syntax)

  3. presumably better maintained (I have not been using
     what's in git's contrib/ directory for some time in
     favor of the upstream version)

This patch gets rid of our local version and just points
interested parties to the upstream version.

-To syntax highlight git's commit messages, you need to:
-  1. Copy syntax/gitcommit.vim to vim's syntax directory:
+Syntax highlighting for git commit messages is included with the vim

+If you have an older version of vim, you can get the latest syntax file

+
+To install:
+
+  1. Copy gitcommit.vim to vim's syntax directory:
      $ mkdir -p $HOME/.vim/syntax
      $ cp syntax/gitcommit.vim $HOME/.vim/syntax
   2. Auto-detect the editing of git commit files:
      $ cat >>$HOME/.vimrc <<'EOF'
      autocmd BufNewFile,BufRead COMMIT_EDITMSG set filetype=gitcommit
      EOF
