[bug #61646] [me] line numbering doesn't work as documented

[G. Branden Robinson]

Follow-up Comment #5, bug #61646 (project groff):

Here's how roff(1) behaved on Unix V7, which is as far as I care
to chase this particular goose.  I "ported" my me(7) input
document to the old system.  I also killed the vertical margins
and shortened the page length.

Input:

$ cat > n1n2.roff
.pl 19
.m1 0
.m2 0
.m3 0
.m4 0
.ll 60

The roff(1) manual says that `n1` and `n2` "add 5 to the page
offset" and that is indeed what they do.

I will adapt my changes accordingly.
