Log Message:

Improve handling of hyphenation patterns.  It is now possible to
use most of TeX's pattern files unmodified.  To make the process
more flexible, a new request `hpfcode' has been added which
provides a character code mapping for the `hpf' request.  See
comment before hpf_getc() for more details.

* src/roff/troff/ (insert_hyphenation, hpf_getc): New
(read_patterns_file): Additional parameter for exception dictionary.
Extended to recognize \pattern, \hyphenation, and \endinput.
(do_hyphenation_patterns_file): Updated.
* src/roff/troff/env.h (hpf_code_table): New extern.

* src/roff/troff/ (hpf_code_table): New array.
(init_hpf_code_table, hyphenation_patterns_file_code): New
(hyphenation_code): Handle translation from `trin' correctly.
(main, init_input_requests): Updated.
(charinfo::set_translation): Handle hyphenation code also.

* src/roff/troff/charinfo.h (charinfo::get_translation_input): New
inline function.

* src/roff/troff/ (WORD_MAX): Reduced to 256 since `unsigned
char' is used for offsets in hyphenation exceptions.

* tmac/ Replace with contents of unmodified `hyphen.tex'.

* NEWS, man/, man/ Document it.

* doc/groff.texinfo: Document possible conflict between `tr' and
`char' requests.
