Equivalent to "mailstored -1" or "mailstored <player> -1", this emails
the moves of your most recent game (or someone else's).
To have every one of your games automatically mailed to you, after each one
is played, do "set automail 1". To stop this option, do "set automail 0".
The mailformat variable determines the format of the mailed games. Do
help vars for more information.
