Subject: [PATCH] Make sure length bytes are two chars wide

Linux bash internal printf shortened the string
when using len2twobytes() with 3 chars, FreeBSD
e.g. did not.

It worked under both OS though when piping to
the socket with printf.

This commit makes sure that always 2+2 chars
are returned when a 3 char number is supplied.

Kudos @dcooper16
