bug#40967: 27.0.50; vc-diff in indirect buffers

[Nathan Moreau]

Here is a new version of the patch, with support for most of the
commands defined in vc.el.

The support is not exhaustive as I was not able to make all commands work
I did not succeed in testing all the commands: vc-delete-file and
vc-rename-file are probably candidates next.

Feedback is very welcome, I am not used to the contribution process on Emacs.
