[bug #55155] [troff] .tr is applied to the RHS of .char definitions

Follow-up Comment #6, bug #55155 (project groff):

True.  For the cited example, the behavior seems clearly wrong.  In the
general case, it may be less obvious what should happen.

.tr zx
.char \(zz zeezee
\(zz top

Is this expected to output "zeezee top" or "xeexee top"?

The manual explicitly says a glyph defined by .char can be the source or
target of a .tr, and that .char itself is nonrecursive, but this particular
interaction does not seem to be directly addressed.
