Feature request: Allow extracting revisions into directories

Hello!

git currently has the archive command that allows to save an arbitrary revision into a tar or zip file. Sometimes it is useful to not save this revision into an archive but to directly put all files into an arbitrary directory. Currently this seems to be not possible to archive directly; the only way I found to do it is to run git archive and then directly unpack the archive into a directory.

    git --git-dir REPO archive REVISION | tar x

It would be nice to have a command or simply a switch to git archive that allows the user to put the files of REVISION into a directory instead of making an archive.

Thank you very much for your help. Yours,
