patch for usr.bin/awk/awk.1 to clarify the use of FS

I realise that awk is a contributed package, but the man page for it has been
pulled in from OpenBSD, and has since been locally modified:
https://svnweb.freebsd.org/base/head/usr.bin/awk/awk.1?view=log

Anyway, the man page assumes that apart from the exceptions mentioned, the FS
is a regular expression. This is not the case for a single character - A single
character FS is considered literal.

Attached patch clarifies this. Note that the man page for gawk is correct on
the subject.

Cheers
