No, I'm (mostly) not using git, but fossil. There is a vc backend for
fossil controled files which provides useful things like vc-diff, but
doesn't has as mighty commit features as magit. I prefer to use the
command line to do the check-ins.

The paragraph above includes one bit of information, that I've missed to
provide, so far. Emacs knows, that the buffers (files) I'm interested in
are under version control.

Since emacs show me in the mode line of that buffers, that the file is
under version control, there must be a way with elisp to determine, if
the file shown in a buffer is under version control. How could that be
done?
