[9fans] acme crash.

[9fans] acme crash.

[Dan Cross]

When I (accidentally) tried to Put an unwritable file, acme commited suicide.
I have to do my taxes, and so haven't tracked all this down, but here's a
stack trace and the error message.  This is after a fresh pull from sources
this morning.

At least trump makes these things easy to figure out.
Another completely different bug in runevsmprint.c.
This time I forgot to multiply by sizeof(Rune) when
reallocating the buffer.

I was about to send in the same (sans stacktrace since its going to be
easily reproducible). I say let Russ sort it out!!! :-)

Once, when I was still a student at Penn State, a friend's ska band was
playing a local show where they offered to give away, ``Trump: The Game''
to the person who could do the best M.C. Hammer dance.  I came in 2nd.
