[bug #64484] [troff] \X escape sequence should read its argument in (something like) copy mode

[G. Branden Robinson]

Follow-up Comment #18, bug #64484 (group groff):

Stop the presses.  Sure enough, as soon as I pulled the trigger on that reply
I realized one reason why there was a difference in output from your
_printf_s.

Try these:


$ printf  ".ft U-TR\n\X'ps: αβγabc'\nαβγabc"|./build/test-groff -Tpdf
-Kutf8 -Z >| deri-64484-escape.grout2
$ printf  ".ft U-TR\n.device ps: αβγabc\nαβγabc"|./build/test-groff
-Tpdf -Kutf8 -Z >| deri-64484-request.grout2
$ cksum deri-64484-escape.grout*
3560394002 244 deri-64484-escape.grout
3560394002 244 deri-64484-escape.grout2
$ cksum deri-64484-request.grout*
1169764700 237 deri-64484-request.grout
1169764700 237 deri-64484-request.grout2


There was a `\c` missing after your `\X` escape sequence.  A newline at the
end of a text line puts a word space on the output--a word space that the
`device` request exhibit didn't have.

There still a difference, but it's less.

I'm not sure how material this is.
