- Fix an issue with the up arrow key in Emacs editing mode.
Emacs editing mode is bugged in ksh93u+ and ksh2020. Let's
say you were to run the following commands after starting
a fresh instance of ksh:
$ alias foo='true'
$ unalias foo
If you type 'a' and then press the up arrow on your keyboard,
ksh will complete 'a' to `alias foo='true'` by doing a reverse
search for the last command that starts with 'a'.
Run the alias command again, then type 'u' and press the up
arrow key again. If ksh is in Vi mode, you will get `unalias foo`,
but in Emacs mode you will get `alias foo='true'` again.
All subsequent commands were ignored as ksh was saving the first
command and only based later searches off of it.
