across several packets. This is done by not turning off buffering
on the stdio stream for the ident connection. Originally this was
done to avoid reading back what you'd just written into the buffer.
However ANSI C gives a list of functions which should allow you to
safely change direction on a stdio stream, and Wietse found that
fseek seemed to be the most portable.
The original patch used a different workaround, but this should be
a real fix.
