Actually "showing HTML pages upon 'git help' request" makes
sense even on Unixen. I think a patch to help.c::cmd_help()
that allows the user to specify alternate action before going to
the codepath to call show_man_page(help_cmd) would make sense,
like the attached patch.
Having said that, a patch that makes the build procedure depend
on the presense of the html branch is unacceptable, as that
branch does not even exist in my private build repository. If
you are building html pages from the source, it surely would
make sense.
