Carsten means if the register holds a value that's already been
converted to base units then append a u.  If it holds inches, for
example, then append an i.

    $ nroff | grep .
    .nr n 3 
    foo
    .br
    .in \nni
    bar
    foo
                                  bar
    $

A smaller test case would be better for those of us pressed for time!

Or `make template all'.  ;-)

No, see section 3 of CSTR 54 and

    info groff | less +/'Request: .po \[offset]'

72,000 looks to be an inch worth of millipoints given a PostScript
output device.

Cheers, Ralph.
