+	(as_string): Likewise.
+	* tbl/table.c: Removed definition of INT_DIGITS.
+	* eqn/box.c (box::top_level): Use INT_DIGITS + 1 instead of 12.
+	* troff/input.c (input_input_requests): Likewise.
+	* ps/ps.c (make_encoding_name): Likewise.
+	(ps_printer::set_style): Likewise.

+
+Sat Jul 21 12:45:07 1990  James Clark  (jjc at yquem)
+
+	* tbl/table.c: Use ' instead of DELIMITER_CHAR in places where the
+	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::define_bottom_macro): Use REPEATED_VPT_MACRO instead of
+	vpt.
+	(table::do_row): Likewise.
+
+	* tbl/table.c (vertical_rule::print): Prefix the .sp -1 line with
+	TRANSPARENT_STRING_NAME.
+
+	* tbl/table.c (table::init_output): In the table release macro
+	print an error message and don't produce any output if after

+	remove the diversion after bringing it back.
+
+	* tbl/table.c (table::init_output): Define a new macro
+	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+	(table::define_bottom_macro): If TOP_REG is no longer valid, use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.

+	next page as set by the pn request.
+
+	* macros/tmac.an: Redid headers and footers.  Number each manual
+	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
+	registers like Sun.
+
+Wed Jul 18 10:23:31 1990  James Clark  (jjc at yquem)

+	exit_request rather than exit_groff.
+
+	* troff/input.c (exit_groff): Call tok.next() before
+	process_input_stack().
+
+Mon Jul 16 09:47:23 1990  James Clark  (jjc at yquem)
+
+	* troff/env.c: ifdef widow control support on WIDOW_CONTROL.
+	* troff/env.h: ditto.
+	* troff/input.c: ditto.
+
+	* troff/env.c (environment::is_empty): Test pending_lines.

+
+	* 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.

+
+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.
+
+	* troff/env.c (environment::is_empty): Add test for !current_tab.
+
+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
+	compiler.
+	
+	* macros/tmac.an (an-header): Set no-space mode.
+
+	* macros/tmac.an (TH): Start a new page if necessary.
