Patch #244 - 2009/8/9
* refactored storage of saved-lines, providing a configure option to
manage them as a FIFO (actually a circular buffer), improving
performance. Added configure option --enable-fifo-lines to
enable/disable the new feature (it is enabled by default).
* added fastScroll resource, to amuse people who measure terminal
emulator performance by cat'ing large files to the screen.
* modify check in readPtyData from return values to provide exit on
zero-bytes read from pty for FreeBSD, or eliminate high-CPU in
"xterm-hold" processing (discussion with Ulrich Spoerlein, FreeBSD
ports/136686). The check was originally modified to combine
negative/zero values in XFree86-3.1.2E, 1996/05/06.
* add configure option --enable-16bit-chars to provide
wide-characters with 16-bits (rather than the default 32-bits).
* add retryInputMethod resource to allow configuring out the retries
xterm uses to connect to non-responsive XIM server, to work around
defective X configurations as noted in [248]NetBSD mailing list.
* make regular-expression selection work for VT100 double-sized
characters.
* improve layout when drawing missing characters in a proportional
font, e.g., as boxes, to take into account whether they are
double-width (report by Guilbert Stabilo on comp.unix.shell).
* add capability for keypad-center (kb2/KA2) to termcap entry for
xterm-new, as well as xterm-8bit, xterm-sun and xterm-vt220
(FreeBSD conf/136336).
* change default for keepSelection resource to true (prompted by
discussion with David Muir Sharnoff).
* remove a limit-check in ptydata.c, allowing Unicode values past 64k
to be displayed using TrueType fonts (Debian #458432).
* remove a vt52-specific ifdef to allow mapping F1-F4 to PF1-PF4 when
vt52 support is not compiled (report by Olaf 'Rhialto' Seibert).
* save/restore line-wrapping flags when converting from ISL-8859-1
encoding to UTF-8 encoding, as well as when resizing screen.
* remove extra adjustment of position in fix for Debian #418324.
* modify default check for mkWidth resource to check for line-drawing
characters, which are categorized as double-width in Solaris 10
(report by Sebastian Kayser).
* add "print-everything" action (patch by Ovidiu Gheorghioiu).
* start refactoring scrollback data using new getLineData() function.
* demote recent change to Debian #252873 fix to experimental, ifdef'd
out as EXP_BOGUS_FG (Debian #522141).
* work around groff mapping of ASCII quotes using macros (requested
by Reuben Thomas based on Colin Watson advice, fixes Debian
#378700).
* correct symbol used for default of allowWindowOps which was
DEF_ALLOW_FONT rather than DEF_ALLOW_WINDOW (report by Matthieu
Herrb).
* amend fix for tek4014 from [249]patch #243 to make it only apply to
the Tek Options menu.
