André did send me already the Tramp logs. I would say Tramp behaves as
expected; I didn't see a problem there.

I don't use git myself, so it would be a little bit harder for me to
test. But scanning vc-git.el, I've seen it applies `call-process'. This
cannot work on remote hosts. I guess it must be replaced by
`process-file', plus adapting the file names used as arguments, because
likely they will be in Tramp syntax.

I would be willing to do the tests, but this might take a couple of
days, because first I must teach myself git first. If somebody is faster
than me, please run.

Btw, `call-process' or `start-process' are used also in vc.el,
vc-arch.el, vc-hg.el and vc-bzr.el. Likely this shall be reviewed, too.
