Don't indent non-numbered lines in nl(1)

This is yet another GNU-specific behaviour we fell for.
POSIX explicitly states that for non-numbered lines, all indentation-
crap should be dropped immediately. Well, we didn't listen, so this
commit will set things straight again.
Honestly speaking, this also looks much cleaner than before.
Fuck GNU!
