For the log:
- David Korn is working on an improved version of the TAB-TAB patch for
ksh93r+ which should add this functionality to both "emacs"/"gmacs" and
"vi" editing modes
- The idea of adding a default editing mode needs little bit
investigation whether this causes problems for terminals with builtin
editing modes (I didn't see any of these in the last ~~ten years... but
maybe they are still being used). If it causes problems we may simply
probe whether ${EDITOR} was set to an empty string (I can update the
patch on demand)
- David/Glenn: it would be nice to integrate the patch for
lib/libshell/common/sh/init.c (the default mode thing) into ksh93r+ (it
will remain inactive unless someone #defines |SHOPT_DEFAULTEDITMODE| at
compile time), assuming it's harmless (see previous item).
