Interesting idea. I just tried a gross hack:

 * Use `make --always-make ... install-man` in doc-diff.
 * ./doc-diff -f HEAD HEAD # note -f
 * Add empty commit and tweak config.mak
 * ./doc-diff HEAD^ HEAD # note no -f

There are lots of irrelevant differences in the headers and footers,
which is a bit unfortunate.

Also, lots of annoying differences originating in Asciidoctor's
inclination to render a space after linkgit:foo . There are those
differences themselves, obviously, but also follow-on differences such
as entire paragraphs that wrap differently.

I could spot a few things that should be fixable on our side, but on a
quick skimming, I didn't spot too many "huge" differences, which feels
good. The one which this patch fixes, obviously, and there's some work
to do in git-status.txt and git-column.txt (at least).

Tacking on `--stat` to the call to `git diff --no-index` singles out
git-config.txt, but it seems like lots of small or maybe even irrelevant
differences, plus lots of spaces around linkgit: , as already mentioned.
