Log message:

Fix buffer overflow problem; tune lengths fed into ircd_vsnprintf() to take
into account the fact that ircd_vsnprintf() already takes \0 into account.

Testing:

The old hack code to test for this buffer overflow is still in place,
intentionally, to catch any other problems that may crop up.  Otherwise,
this code has been compiled and tested and produces the correct results--
never knew I could write a simple client that rapidly ;)
