I haven't updated the one I made just before 3.1.9, but I don't think
everything on that last list got done, either.

I meant to reply to that message.  I've never been happy with using the
exit status to indicate that an ->state action was taken.  The only
simple test on exit status is true/false; for anything else, you have
to compare against $? -- which means you might as well be testing some
other parameter instead, e.g. [[ -n "$state" ]] which is what most of
the functions that use ->state already do anyway.

So I suggest simply dumping the 300 exit status; zero means that matches
were added, anything else means that no matches were added, and if you
want to use states you test the $state array directly.

}   There is no way to handle ^D at the beginning of the line with a
}   widget, because the zle main loop deals with it directly.

It *is* possible to handle ^D at beginning of line:  stty eof undef
permits it.  This is equivalent to having to turn off flow control in
order to use ^S and ^Q in keybindings.

So maybe the right answer is that `setopt ignoreeof' should affect ZLE
the same way that `setopt noflowcontrol' does.  An actual zero-byte
read would still be handled as it currently is; only ^D in column zero
would be different (actually invoke the ^D binding rather than print
"zsh: use 'logout' to logout.").

THEN we could change delete-char-or-list to print that warning when there
are no characters in the editor buffer, et voila: the default behavior is
exactly as now.

I've been toying with the idea of adding a "user contributions" chapter
to the manual and throwing into it: incremental-complete-word, zed, the
prompt themes, predict-on, zrecompile, nslookup, etc.  With appropriate
sections, of course.

There's also 11468.  I wish I had a suggestion.
