To complement RM (read next message), we have added
DM (delete message), which attempts to delete the message
you've most recently read.

DM requires no argument, unlike DELMSG. So just type
DM, and it should delete the message you just read.

DELMSG is still there so you can delete a specific
message by message number (e.g. DELMSG 42).
