C-x C-s does a save without the expunge.

It's not that simple.  There's some kludgery involved in keeping
vm-buffer-modified-p up to date, and the save function wrappers
are part of that kludgery.  I could get rid of it all there was a
way to have a read-only folder and still have some way to
displaying on the mode line whehter the buffer has been modified.
