The overloading of IR emits magic \X'...' sequences that turn into HTML manual links.
But not all such IR invocations should be manual links;
those had to be written to avoid the IR macro before.
Worse, the \X'...' ending the IR causes troff to emit only a single space after a period.
Defining a new IM macro for manual references fixes both problems.
Fixes#441.
List mode was constrained to the BMP. This change introduces
the following new list mode convention, using Go string literal syntax:
Non-printing ASCII characters display as \xhh.
Non-ASCII characters in the BMP display as \uhhhh.
Characters beyond the BMP display as \Uhhhhhhhh.
Also, if CC9FLAGS includes -fsanitize=address (ASAN),
predefine PLAN9PORT_ASAN for use by programs that need
to know (mainly libthread).
The 9c script used to have a variable called ngflags, which
was ccflags except -g (ng stood for "no g"), but nothing needs
it split out anymore, so simplify to just ccflags.
This fixes at least one shell script (printfont) that expected
'x'`{y}'z'
to mean
'x'^`{y}^'z'
as it now does. Before it meant:
'x'^`{y} 'z'
One surprise is that adjacent lists get a free carat:
(x y z)(1 2 3)
is
(x1 y2 z3)
This doesn't affect any rc script in Plan 9 or plan9port.

Rename following .cvsignore files to .gitkeep since they are
required by the build (directories must exist before build):
- bin/fossil/.gitkeep

This is an experiment.
Like tpic it's a copy-and-paste fork of pic.

Ignore scroll/noscroll window setting.
Instead, scroll when the write begins in
or immediately after the displayed window content.
In the new scrolling discipline, executing
"Noscroll" is replaced by typing Page Up or
using the mouse to scroll higher in the buffer,
and executing "Scroll" is replaced by typing End
or using the mouse to scroll to the bottom of
the buffer.
