Update to version 3.113. Major changes were to incorporate FreeBSD-
specific changes into the original distribution (although sometimes
with a slightly different approach) and to add two commandline
options to send-pr(1):

-c which allows you to specify an address to CC this
PR to
-s allow the severity to be specified on the commandline
