This depends on GIT-ASCIIDOCFLAGS, which is good. But I think we'd also
want to tell that file whether we are using the direct backend or not.
Otherwise, doing:

  make USE_ASCIIDOCTOR=1 git.1
  make USE_ASCIIDOCTOR=1 USE_ASCIIDOCTOR_MANPAGE=1 git.1

gets confused. Because git.1 is more recent than git.txt, it things
there is nothing to build in the second case. I think you want:

diff --git a/Documentation/Makefile b/Documentation/Makefile
index 536d9a5f3d..4b66a61f51 100644

 GIT-ASCIIDOCFLAGS: FORCE
 	@FLAGS='$(TRACK_ASCIIDOCFLAGS)'; \

With that change, plus a patch I'll send in a minute, it's easy to run
doc-diff on the result.

Unfortunately, this doesn't seem to work. Diffing the rendered docs
between regular asciidoctor-then-xmlto and direct-to-manpage shows a lot
of hunks like:

              For more details about the <pathspec> syntax, see the pathspec
  -           entry in gitglossary(7).
  +           entry in \fBgitglossary\fP\fR(7)\fP.
