IRC appends a trailing space to messages

[geofft@mit.edu]

It appears that if you write a message of the form

hello
.

the IRC routines will send it as hello , with a trailing space, probably because it's turning the newline into a space. Sending it by typing hello followed by a Ctrl-D with no newline makes it not have a trailing space.

(noticed by a bot that was picky about parsing and got confused at the extra space)
