[BUG] yet another doc formatting problem

[Jeff King <peff@peff.net>]

When I build git-rm.1, some of the headings look odd. For example:

   Using  git commit -a""
          If you intend that your next commit should record...
   ...
   Using  git add -A""
          When accepting a new code drop for a vendor branch

Note the funny double-space and the weird "" at the end. I get the same
thing from "git show origin/man:man1/git-rm.1 | nroff -man".

The source looks like this:

  $ git grep -A1 Using..git.commit git-rm.txt
  git-rm.txt:Using "git commit -a"
  git-rm.txt-~~~~~~~~~~~~~~~~~~~~~

which looks sane to me. The generated xml also looks OK to me:

  $ grep Using..git.commit git-rm.xml
  <title>Using "git commit -a"</title>

But the resulting roff doesn't:

  $ grep Using..git.commit git-rm.1
  .SS "Using "git commit \-a""

which looks like a quoting error to me, which implies a bug in docbook.

I guess we can hack around it with some XSL magic, but I am tempted to
do the simple:

diff --git a/Documentation/git-rm.txt b/Documentation/git-rm.txt
index 71e3d9f..8ee559b 100644

 When accepting a new code drop for a vendor branch, you probably
 want to record both the removal of paths and additions of new paths
 as well as modifications of existing paths.
