fwiw, this was mentioned in
Patch #294 - 2013/07/05
* add note in ctlseqs.ms for CPR response pointing out a potential
point of confusion with the string sent by a modified F1 key
(suggested by Bram Moolenaar).
* improve plink.sh by checking if the linker supports the
--as-needed option (suggested by David Philippi).
* improve clearing for private mode 1049 when switching to the
alternate screen (Debian #711758).
* amend fix from [567]patch #292 by removing now-unneeded chunk
which introduced problem in selection (Debian #714527).
* add definition to optionally override compiled-in class for xterm
from makefile, needed for test-packages.
* add configure option --enable-sixel-graphics
* add experimental support for sixel graphics (Ross Combs).
but overlooked in Debian, for which "apt changelog xterm" tells me that
patches 293 and 295 were noted, but not 294.
