[bug #64484] [troff] \X escape sequence should read its argument in copy

Follow-up Comment #13, bug #64484 (group groff):

Waffling on this.  `\X` seems to be mutating in such a way that it has grown,
alas, a third mode of argument interpretation, neither "normal"
("interpretation") or "copy".

I've just about got the `device` request converted over to the same thing (for
bug #63074) and _nearly_ everything looks very nice.

I blanch at the pedagogical challenge I've created for myself; whatever this
new mode is, likely it will need to apply to the `output` request and `\!`
escape sequence as well.  All of these for the same reason: there's stuff,
foremost "nodes", that have representations inside the formatter but none
outside of it.  And the whole point of these escape sequences and requests is
to slip the surly bonds of the formatter, seizing the yoke from it and
attempting to fly the device-independent page description language oneself.

Little wonder that such attempts usually end with a swift embrace of the
ground.
