Fixed a bug which prevented hyphenation of words which are finished

with `)'.

* src/roff/troff/token.h (token): Add enum type
`TOKEN_TRANSPARENT_DUMMY' and method `transparent_dummy()'.
* src/roff/troff/input.cc (token::next, token::description,
get_line_arg, token::add_to_node_list, token::process): Use it.


* src/roff/troff/div.h (diversion): Add `saved_prev_line_interrupted'.
* src/roff/troff/div.cc (do_divert): Use it.

* src/roff/troff/input.cc (asciify): Add ESCAPE_RIGHT_PARENTHESIS.
