A new escape sequence `:', inserting a zero-width break point.
* src/roff/troff/input.h: Adding `ESCAPE_COLON'.
* src/roff/troff/input.cc (get_copy, token::next, asciify):
Implement it.
* src/roff/troff/node.h (node): Add `is_escape_colon()' virtual
method.
(space_node): Add `was_escape_colon' member. Add `is_escape_colon()'
and `asciify()' methods.
* src/roff/troff/node.cc (space_node::space_node): Updated.
(space_node::asciify): Handle `was_escape_colon'.
* NEWS, src/roff/troff/troff.man, man/groff.man: Document it.
Handle `~' similar to other comparable requests.
* src/roff/troff/input.cc (process_input_stack): Remove now obsolete
label.
(token::next): Move creation of an unbreakable_space_node to...
(token::add_to_node_list): Here.
Fix a bug which sometimes prevented hyphenation of words connected
with `~' or ` ' (and other escape sequences handled as
TOKEN_NODE). This also fixes a hyphenation problem with boxes
(after a call to the `unformat' request).
* src/roff/troff/env.h (environment::possibly_break_line,
environment::hyphenate_line): Introducing `start_here' parameter.
* src/roff/troff/env.cc (environment::space_newline,
environment::space): Use it.
(environment::possibly_break_line, environment::hyphenate_line):
Implement it.
* src/roff/troff/input.cc (process_input_stack): Use it.
* src/roff/troff/node.h (unbreakable_space_node, hmotion_node,
space_char_hmotion_node, overstrike_node): Add
`get_hyphenation_type()' method.
* src/roff/troff/node.cc (break_char_node::asciify): Don't asciify
if `unformat_only' is active.
Implemented new read-only number register `.linetabs' which
returns 1 if in line-tabs mode, 0 otherwise.
* src/roff/troff/env.h (environment): Add get_line_tabs() member.
* src/roff/troff/env.cc (get_line_tabs): New function.
(init_env_requests): Use it.
