vc-do-command: Fix last part of 'full-command'

* lisp/vc/vc-dispatcher.el (vc-do-command): Don't append " ." to
'full-command' when FILES is nil because the command we actually
run doesn't have "." as a final argument in that case.

(cherry picked from commit 8897c15251a4374145083d2995a61fae2806238f)
