I used this technique in my talker server, which receives bits of data
from each client, but only triggers the processing of a line when it
receives a new line character.  It's *much* faster than doing it the
easy way, even for reasonably short strings that you might receive at a
few bytes at a time (such as a short sentence that somebody says.)

Things started getting a little complex when I needed to stoop the
contents of the string stack for telnet codes, but otherwise, I'd
recommend doing this to anybody who needs to process strings of unknown
length.
