Patch #372 - 2022/03/09
-amend allocation/freeing of scrollback lines, eliminating an adjustment for
status-line added in patch #371 (report/testcase by Rajeev V. Pillai).
Patch #371 - 2022/02/24
-drop double-buffer default from test-packages, since that interferes with
status-line.
-add faceSize7 to table in charproc.c, overlooked in patch #360 (patch by
Vladimir A. Pavlov).
-use XDrawString rather than XDrawString16 for text when the latter is not
needed.
-improve performance for initializing/reusing graphic objects in the SIXEL
feature.
-improve error-checking for resize.
-fix errata in manual page (Debian #988221).
-extended list of environment variables to purge on startup, i.e., in case a
user starts xterm from another terminal emulator.
-add comment in cursor.c to explain why autowrap (DECAWM) does not apply to
data saved/restored with save/restore cursor-operations (report by Thomas
Wolff).
-add special case in generating the combining-character table in wcwidth.c,
for Hangul Jamo Extended-B (report by Luis Javier Merino).
-simplify/improve portability of trap commands in shell-scripts.
-update configure options
--disable-rectangles,
--disable-tcap-fkeys and
--disable-tcap-query
to account for changed default settings.
-rather than ignore empty parameter for setting title, use that to reset it
to “xterm” for scripting.
-check for out-of-bounds condition while drawing sixels, and quit that
operation (report by Nick Black).
-add fallback definition for PROJECTROOT so that a suitable default location
for luit will be compiled-in on build-servers.
-implement DEC status-line controls DECSASD/DECSSDT:
decode controls, set state
implement DECRQSS responses
implement indicator-style status-line
add configure option --enable-status-line
add resource indicatorFormat
implement host-writable status-line, able to handle video-attributes and
simple left/right cursor movement. This disallows all of the DEC/xterm
private modes such as switching to/from the alternate screen.
move the status-line if the window is resized.
Note: the associated screen-resizing does not work for the special case
of TrueType fonts with double-buffering (see note in patch #349).
-modify configure-script fixup for -Werror options to exclude fixup for
-Werror=format, e.g., -Werror=format-security.
-amend change from patch #370; DEC 070's pseudo-code for DECCOLM incorrectly
suggests that it enables DECLRMM as a side-effect.
-fix some memory leaks seen using esctest and asan2 (patch by Luis Javier
Merino).
