:) This works, thanks, as well as the gitk patch 2/2, which is difficult
to cover by test scripts. Some OSes (or rather certain setenv/putenv
variants) have problems distinguishing an unset variable from an empty
one. I think we've worked around this, but avoiding it is safer, as J6t
pointed out.

Thanks!
Michael
