src/roff/troff/env.cpp: Avoid infinite loop.
* src/roff/troff/env.cpp (environment::possibly_break_line): Emit break
warning and return if the output width is not positive. The code
assumes that it will be and loops infinitely if it isn't. I _think_
this is because we're not able to get width data for (some?) CJK
glyphs. Based on a patch by Osamu Sayama.
Fixes <https://savannah.gnu.org/bugs/index.php?44018>.
