I think the problem is that make-auto-save-file-name uses make-temp-name
for buffers that aren't visiting files, and that uses the mktemp C function,
which returns a different result for every subsequent call.  This makes
make-auto-save-file-name unsuitable for mail-recover, because it can't
reliably determine the Mail buffer's auto save file.

Perhaps make-temp-name could use a (MD5?) checksum on the buffer contents
for such buffers, instead of mktemp.
