Sadly, (or gladly? :) none of my ssh clients have given me trouble wrt
version strings. :-/ If you have gone through the source, that is about
as much as I can do too.. I suggest something similar to: SSH-1.5-99 or
SSH-2.0-0 -- based on the code, anyway. (I'm not very good at C...)

On an only slightly related note, could someone with more experience
please look at /usr/src/usr.bin/ssh/sshd.c, starting roughly 296 lines
into the source...

One `if' statement uses `break', the other `continue'. I'm not entirely
sure why it would do different things depending on the next character
being \r as compared to \n. Like I said, if someone with experience
could look this over, it would make me feel better. :)
