installing git man pages quickly

I just upgraded git to get a fix for a diff buffer overflow. I built the git binaries, but this box is too slow to rebuild the man pages.

Fortunately those are already prebuilt in a separate branch. One way to install them without rebuilding them locally is to:

    # in a clone of git://git.kernel.org/pub/scm/git/git.git
    
    git archive --format=tar origin/man | sudo tar -x -C /usr/share/man/ -vf -

… with which I don’t have to rebuild man pages locally. Git rocks!
