The problem with not showing something in VC buffer is a common one for
asynchronous VC commands (diff, log).  The solution we have in emacs-23
for that is to add [Working...] on the modeline while such command is in
progress.  Was that not obvious enough?  Does the face for that message
need to stand out a bit more?

Please feel free to fix the doc string the way you want it.
