I think one reason it was "meh" for me is that we never did an equivalent of "cvs export" and "svn export", primarily because we had "tar-tree" (aka "archive --format=tar") first, and it was sufficient to pipe its outputto "tar xf -" if somebody wanted to do the non-existent "git export". Also "tar-tree" was more useful for people who wanted to eventually want to have a tarball (you can first "export" and then "tar cf" the resulting directory).

But I think it is fine to add "git export <revision> <directory>", which may look like this, perhaps.

	#!/bin/sh
	# git export <rev> <directory>
	rev=${1?revision} dir=${2?directory}
	. $(git --exec-path)/git-sh-setup

        mkdir -p "$dir" || exit
        git archive --format=tar "$rev" |
        tar Cxf "$dir" -
