Jon Forrest, wanting roman page numbers centered at the bottom of each
page using -ms, writes:

I suspect that you actually tried ".af PN i" in the above sequence,
found that you got ordinary page numbers, then tried ".af % i", and
THEN found that you got none.  I can't reproduce the above, anyway.

But I can produce the desired effect, like this:

	.ds CH
	.ds CF \\n(PN
	.af PN i

The % character that you put into the string CF causes the insertion of
the page number because \*(CF ends up being used in a .tl request, and
the character % (or such other character as is specified by .pc) in a .tl
is taken as \n%.  That is, it uses the internal page number number register,
named %, directly.  But changing the format of number register % to i doesn't
work either, because \n% is also used by -ms in numeric contexts, and must
have a numerical format there.

Putting a direct invocation of the PN number register into the string CF, as
shown above, does work.
