I've just tried comparing zsh with all patches up to but NOT including
11503, against zsh including 11503, and I see no differences between
those (maybe 11493 had an effect?).  So then I compared zsh including
11503 against zsh patched up to 11471 (e.g. code-wise should be identical
to -pre-4).  The newer zsh does NOT show the behavior above; the older
one does.

Since the newer version doesn't have the bad behavior, the following is
mainly for information, in case a light bulb goes on above Sven when he
sees it.

The test case was to run `vared functions[_complete_debug]', scroll up
to the line `local w="${(qq)words}"', then type ^E ESC RET to open a
line, and begin completing on that line.

If I immediately type ^X?, both versions beep at me.  Comparing the xtrace
output, the ONLY difference shown (other than line numbers) is the value
assigned to the _saved_colors local, which is irrelevant.  Both versions
output the string from _message.

If I start the test again from a fresh PS1, but type TAB and then ^X?,
zsh-11502 produces the same xtrace as before, but zsh-11471 has this
additional fragment:

+_main_complete:41:if: [[ tab automenu-unambiguous == tab* && _complete_debug != *list* ]]
+_main_complete:42:then cursh: zstyle -T :completion::::: insert-tab
+_main_complete:43:then cursh cmdand cursh: [[ ::: != :* || -z functions[_complete_debug] ]]
+_main_complete:44:then cursh cmdand cursh cmdor: zstyle -t :completion:vared:::: insert-tab
+_main_complete:46:then: compstate[insert]=automenu-unambiguous 

In this particular test they also both output the message, so I still
don't know exact steps to reproduce sending it into command completion.
