Actually, I had no such change in mind. IMHO the right fix is to
eliminate the fixed-width fields entirely. I see no good reason why
the startup packet shouldn't be several null-terminated strings with
no presupposed lengths. In most cases that would actually make the
packet shorter than it is now.
We'd probably want an overall sanity-check limit on the packet size,
but it could be of the order of 10K without any problem that I could
see.
