Retire git-export.
git-export was done as a concept example on how easy it is to export the git data to something else. It's much less powerful than any number of trivial one-liner scripts now, and real exporters would not ever use git-export. It's obviously much less powerful than "git-whatchanged", or just about any combination of git-rev-list + git-diff-tree. Signed-off-by: Junio C Hamano <junkio@cox.net>
