Sorry I'm not capable to do this. That's the reason I called it
a wish list bug.
Because of your suggestion I have fiddled around a bit and found
a workaround which somehow supports your suggestion::
I initilalised an empty repository ~/.git. Now vc "considers"
my whole home directory as potentially version controlled and
interacts with git. Git in turn honours the environment
variables and voila: many of the vc-commands are working now.
Since I do not want to use this ~/.git I did a
chmod -R a-w ~/.git
in order to prevent accidentially using this repository in stead
of one of the detached ones.
Thanks for the hint.
Gregor
