In man(1) mode, when the first argument starts with a digit,
optionally followed by a letter, and at least one more argument
follows, interpret the first argument as a section name even when
additional characters follow after the digit and letter.
This is needed because many operating systems have section names
consisting of a digit followed by more than one letter - for example
Illumos, Solaris, Linux, even NetBSD.
There is very little risk of regressions: in the whole corpus of
manual pages on man.openbsd.org, there isn't a single manual page
name starting with a digit. And even if programs like "0ad" or
"4channels" had manual pages, "man 0ad" and "man -a cat 0ad" would
still work, only "man -a 0ad cat" will fail with "man: No entry for
cat in section 0ad of the manual."
Fixing one of the issues reported by Lorenzo Beretta <loreb at github>
