[bug #55155] .tr is overzealous in nroff output

[Dave]

Follow-up Comment #2, bug #55155 (project groff):

It turns out commit babca15fa2d3f5ec1dd7214e31e1efc42759c220vax solved this
specific instance of the problem by changing how nroff displays a dagger
symbol.  So the examples below do not fail in the manner described using the
latest groff code and .tmac files.

But the general problem -- that .tr sometimes changes characters that don't
actually appear in input -- remains.  Using the latest tmac/tty-char.tmac, for
instance, you can get the result:

$ printf '.tr n-\nA \[if] B\n' | nroff | head -1
A <i-fi-ity> B

.tr should only change n's that appear in input, not ones that appear only in
output, and especially not ones part of a predefined symbol.
