src/roff/troff/input.cpp (do_if_request): Boolify.
* src/roff/troff/input.cpp (do_if_request): Boolify. Demote `result`
from `int` to `bool`. Assign Boolean literals to it.
Also annotate null pointers with `nullptr` comment to ease any future
transition to C++11, which defines it as a keyword.
Also wrap long input lines.
