* driver/printer.h (printer::draw), driver/printer.c (printer::draw),
ps/ps.c (ps_printer::draw), dvi/dvi.c (dvi_printer::draw): Make
type of first argument int rather than char. This works around a
bug on the 68030 based Apollo using g++ 1.37.1.
* tbl/table.h (class table): Add `keep' member.
* tbl/table.c (table::table): Initialize `keep'.
(table::add_vertical_rule): Set `keep' to 1.
(table::do_top): Only emit table keep macro is `keep' is non-zero.

Tue Jul 24 08:35:07 1990 James Clark (jjc at yquem)

Mon Jul 23 10:15:23 1990 James Clark (jjc at yquem)
* lib/font.c: Initialize font::hor and font::vert to 1.
(font::load_desc): Check the values of font::hor and font::vert.
* lib/lib.h: Added definition of INT_DIGITS. Fix it so that it can
be included in a C compilation.
(iftoa): Use INT_DIGITS. Include lib.h.
* tbl/table.c: Removed definition of INT_DIGITS.
* eqn/box.c (box::top_level): Use INT_DIGITS + 1 instead of 12.

argument to \w is at a different input level.
* tbl/table.c (table::init_output): Define a new macro
REPEATED_VPT_MACRO, like vpt but if in a diversion also
transparently outputs itself.

(table::do_row): Likewise.
* tbl/table.c (vertical_rule::print): Prefix the .sp -1 line with
* tbl/table.c (table::init_output): In the table release macro
print an error message and don't produce any output if after
issuing the need request the table still will not fit. Also
remove the diversion after bringing it back.

REPEATED_MARK_MACRO, like mk but if in a diversion also
transparently outputs itself.
(table::do_row): Mark row_top_reg using REPEATED_MARK_MACRO. This
is necessary because .TH might not call .T#.
(table::do_top): Likewise TOP_REG.
(table::define_bottom_macro): If TOP_REG is no longer valid, use
#T - DOUBLE_LINE_SEP rather than #T. This is necessary because the
table header might contain just the two top rules.
Fri Jul 20 10:51:42 1990 James Clark (jjc at yquem)
* troff/div.c: Implement new request `ptr' to print all traps.
* troff/env.c (init_env_requests): Implement `.tabs' reg with

* troff/div.c: New number register .pn returns the number of the
next page as set by the pn request.

entry starting from 1 unless \nC is > 0, like Sun. Added an
optional 5th argument to .TH which specifies the manual name and
appears in the center of the header. Understand the X, P and D

page_character to input.c also.
* troff/env.c (title): Split off the reading of the parts of the
title into read_title_parts.
* troff/input.c (read_title_parts): New function. Check the
input_level when testing whether a token matches the delimiter.
* troff/input.c (exit_request): New function.
* troff/input.c (init_input_requests): Bind ex request to
exit_request rather than exit_groff.
* troff/input.c (exit_groff): Call tok.next() before

* troff/env.c, troff/env.h: Add automatic widow control feature.
* troff/input.c (exit_groff): Do process_input_stack() after
do_break() but before setting exit_flag to 2.
* troff/input.c: Remove FLUSH_PENDING_LINES and
TOKEN_FLUSH_PENDING_LINES. Instead, flush pending lines from
environment after END_TRAP token seen, but only if there aren't
any more traps still unfinished.
* troff/token.h: Remove TOKEN_FLUSH_PENDING_LINES.
Sun Jul 15 10:50:08 1990 James Clark (jjc at yquem)
* troff/env.c: Rename the `retain_size' member of class
pending_output_line to `no_fill'.
* troff/env.c (title): When the line is output, make the
retain_size argument !fill.
* troff/node.h: Add `hyphenated' member to struct breakpoint.
* troff/node.c (space_node::get_breakpoints),
(dbreak_node::get_breakpoints): Fill this in.
* troff/env.c: Allow specification of maximum number of
consecutive hyphenated lines.

Sat Jul 14 11:23:01 1990 James Clark (jjc at yquem)
* troff/env.c (environment::hyphenate_line): Don't completely give
up if the word is not to be hyphenated; continue so that breaks
can be made at break_char_node's.
* lib/lib.h: Only define INT_MAX if it's not already defined;
undef INT_MIN if it's already defined.
* Makefile: Make it easy to define CFRONT_ANSI_BUG.
* lib/lib.h: If CFRONT_ANSI_BUG is defined, cast INT_MIN to long.
This works around a bug in AT&T C++ 2.0 used with an ANSI C
* macros/tmac.an (an-header): Set no-space mode.
* macros/tmac.an (TH): Start a new page if necessary.
* Started using ChangeLog at version 0.4.
