[Since I've had a couple of people misunderstand what I meant here, I'm
CC'ing this clarification to bug-gnu-emacs.]

M-x mail looks at the *mail* buffer, not the ~/#%*mail*# file.  If the
checkpoint file exists but the *mail* buffer doesn't, M-x mail does not
realize that you might have an unsent message in the checkpoint file.

E.g., if you start composing a mail message and your Emacs dies, if you
start a fresh Emacs and type M-x mail, it will not offer to restore the
previous message.  You can also duplicate this by typing M-x mail,
typing a few characters, killing the *mail* buffer and then typing M-x
mail again (we're running 18.52).

I was suggesting that Emacs know about the *mail* checkpoint file (just
like it knows about other checkpoint files).
