Yes, you are right.

I have another idea: how about if mail-recover shows all the files
whose names begin with "#*mail*#"?  Since nowadays there could be
several such files in the user's home directory, Emacs cannot really
be sure which file to recover, right?  So we should let the user
decide, I think.

Meanwhile, I see that mail-recover has a bug in that it calls `ls'
directly, which will not work on non-Posix platforms (fix, fix).
