[mew-int 00670] Stale .mew-* files

[M. Warner Losh]

Consider the following scenario:

	 1) I look at folder +foo with mew.  It has 500 messages.
	 2) In xterm I do a rmm +foo all.
	 3) Now mew thinks the messages are still there (it shows them
	 in the summary mode when I visit +foo), but they really
	 aren't.

Is there some way to tell mew "The .mew files are bogus, as is your
cached idea of the folder, please rescan."  The only way I've found so
far is to exit emacs, rm the .mew* files and then reenter emacs.
