[PATCH] Correct description of -n/--numeric option

[Jon Jensen <jon@endpoint.com>]

"When used twice" was used twice in the manpage. :)

And as Florian Westphal <fw@strlen.de> pointed out, it was also incorrect
for the -nn case.

Update the manpage and built-in help in main.c to match actual behavior.
