Getting VC to notice updates to a file's status?

Getting VC to notice updates to a file's status?

[Davis Herring]

If I edit a file in Emacs, but then instead of committing it via vc (C-x v
v), I do the commit in a shell, is there a way to ask VC to examine the
file again to see what version it is (now) and to see that it's not
modified?  `revert-buffer' seems to do this (but it loses the undo
history), and C-x v v seemed to do it in versions prior to 23.

Thanks,
Davis

The next Emacs release checks the VC status every time the buffer is
saved. So you can write a letter, delete it, save and the VC status will
be reloaded.

Not elegant, but works and is faster than M-x revert-buffer, plus keeps
the undo history.
