Right, but the quoting convention is straightforward -- just apply a
backslash.  The following should be good enough.  I've tried to apply it
everywhere it could possibly make sense; it should be harmless if it's
not needed.  Just possibly you might get some extra backslashes in
descriptive text, since I haven't attempted to separate that out.

(By the way I don't usually post updates to _perforce since they aren't
of general interest, so it's often worth checking the archive.)
