The prompt string for execute-extended-command is “M-x ”, but that
is not correct if the command is bound to some other key by
customization.
Kevin Rodgers gave this explanation recently in “gnu.emacs.help”:

Change this code in src/keyboard.c and recompile emacs:
/* This isn't strictly correct if execute-extended-command
is bound to anything else. Perhaps it should use
this_command_keys? */
strcat (buf, "M-x ");

So, possibly the promp can be changed to “Execute command ”.
Thanks.

This is no longer done, but it's still not quite right.
If you do:
(local-set-key [(meta z)] 'execute-extended-command)
Then you still get "M-x" as the prompt if you do `M-z'.
The reason is that it looks up the command first, and then picks one of
the bindings as the description, with code that's kinda like this:
(key-description (car (where-is-internal 'execute-extended-command)))
Is there any reason it doesn't just use this_command_keys which
presumably would be more correct?

OTOH, you might get into a tricky situation if execute-extended-command
was launched by, say, a mouse event.

Actually the problem is that it should never have said "M-x " but rather
"Run command: ". From this viewpoint, there's no need to use
this_command_keys: "M-x" is really only meant to be "the canonical
key-binding for this command", so (key-description (car
(where-is-internal 'execute-extended-command))) works as well.
Otherwise if someone happens to hit the "menu" key without realizing
that it's bound to execute-extended-command he might start wonder "OK
the menu bar says 'menu ' what do I do now?", whereas presumably with
"M-x " the user sees "oh that runs the same command as M-x, cool".

Right. So I'm closing this report, since this isn't really a bug.
