Fix the userhostlen' fallback in split_message'

Browse Source 
ferret, the author of `splitlong-safe.pl' pointed out that `userhostlen'
should not only contain the maximum length of the hostname, but also the
maximum length of the username. Now 10 is used as the maximum username
length as a fallback. (`splitlong-safe.pl' uses the same limit.)

The username limit isn't defined in the standard, but 10 is common on
many networks. The odds that something goes wrong here is low, as
 1) the fallback limit is only used when the user has not yet joined a
    channel
 2) the maximum hostname length (63) gives some error margin as the
    hostname usually is shorter
