Why don't you use simply --prefix=DIR?

Well, the infodir part works trivially, because autoconf (and
therefore ./configure script) has support for --infodir=DIR.
Below there is patch that adds that, with the commit message.

But it is more difficult with respect to --htmldir. I am not autoconf
hacker, so I don't know how to add support for having --htmldir=DIR in
./configure (in configure.ac).  What can be done is to derive htmldir
in config.mak.in from other sources, for example:

  htmldir=@datadir@/doc/git

or something like that.

Now that we actually (can) install some info files, and that $infodir
is set and used in Makefile(s), let add support for --infodir=DIR
[PREFIX/info] ./configure option in config.mak.in.

Half of patch by Jeff King <peff@peff.net>m adding --XXdir support 
(the easy part: autoconf has --infodir, but not --htmldir).
