/*
* Notify user when new mail has arrived. [Idea from Merlyn Leroy, but
* I don't know the details of his implementation.]
* { Later note: he disliked my calling a general mailreader and felt that
* hack should do the paging itself. But when I get mail, I want to put it
* in some folder, reply, etc. - it would be unreasonable to put all these
* functions in hack. }
* The mail daemon '2' is at present not a real monster, but only a visual
* effect. Thus, makemon() is superfluous. This might become otherwise,
* however. The motion of '2' is less restrained than usual: diagonal moves
* from a DOOR are possible. He might also use SDOOR's. Also, '2' is visible
* in a ROOM, even when you are Blind.
* Its path should be longer when you are Telepat-hic and Blind.
*
* Interesting side effects:
* - You can get rich by sending yourself a lot of mail and selling
* it to the shopkeeper. Unfortunately mail isn't very valuable.
* - You might die in case '2' comes along at a critical moment during
* a fight and delivers a scroll the weight of which causes you to
* collapse.
*
* Possible extensions:
* - Open the file MAIL and do fstat instead of stat for efficiency.
* (But sh uses stat, so this cannot be too bad.)
* - Examine the mail and produce a scroll of mail called "From somebody".
* - Invoke MAILREADER in such a way that only this single letter is read.
*
* - Make him lose his mail when a Nymph steals the letter.
* - Do something to the text when the scroll is enchanted or cancelled.
