Fix manpage creation error.

When running make_docs.sh, I get the error:
  asciidoc: FAILED: manpage document title is mandatory
  make: *** [git-cherry-pick-upload.xml] Error 1

I don't fully understand why, or why this hasn't come up before, but it
seems to be complaining about the formatting of "===" in
git-cherry-pick-upload.txt. This was with xmlto version 0.0.25 on
Precise.
