Customization of VC commands

Customization of VC commands

[Óscar Fuentes]

I don't see too much provision on VC for customizing commands. Just
today I missed the possibility of setting a variable that would be used
for telling vc-print-log to work across file copies and renames (for
git). Something like vc-git-print-log-extra-options.

Is this intentional or work in progress? Any plans about how to do it?
The only mention of VC on etc/TODO is this:

** Improve VC: yes, there's a lot of work to be done there :-(
  And most of it could/should make it into Emacs-23.3.

VC has the `vc-switches' macro which backends are supposed to use for
that, which provides the user with variables like
vc-git-print-log-switches (which would be just what you asked for).

It's better than nothing, but we'd want to be able to provide/change
such arguments dynamically.

Check existing uses of `vc-switches', and then change the remaining code
to use it as well.
