The formatter behaves unpredictably and weirdly if `fzoom` is given a mounting
position or abstract font name as its first argument.
$ cat EXPERIMENTS/fzoom-position.groff.fam T
.fzoom 1 500 \" or s/1/R/
Times,
.fam H
.fzoom HR 900
Helvetica,
.fam P
.fzoom PR 1200
Palatino,
.fzoom CR 1100
and \f[CR]Courier\f[].
.fam T
Times again.
.br
\F[T]FONT
\F[H]FONT
\F[P]FONT
\F[C]FONT
Take out the first line to observe well-behaved formatting.
The request should reject such attempts with an error diagnostic, and do
nothing.
