* bug#25612: 26.0.50; Slightly suboptimal message for disabled commands @ 2017-02-03 12:34 Philipp Stephani 2017-02-03 13:19 ` Eli Zaretskii 0 siblings, 1 reply; 9+ messages in thread From: Philipp Stephani @ 2017-02-03 12:34 UTC (permalink / raw) To: 25612 Run M-x erase-buffer. The *Disabled Command* buffer that shows up contains You have typed RET, invoking disabled command erase-buffer. This should rather be You have typed M-x erase-buffer RET, invoking disabled command erase-buffer. The RET alone of course didn't invoke the command, it just happens to be the last keystroke, so this message might be somewhat confusing.

Depending on your POV, it could be argued that RET is the one that actually invoked the command.

This is a regression: it still works as expected in Emacs 23.4, but no longer in Emacs 24.3. Probably something about this-command-keys or command-execute changed in the meantime so that the code in novice.el no longer works as expected.

Yes, this-command-keys returns just "^M" instead of the expected "\370erase-buffer^M" it returned in Emacs 24.2 and older. ^ permalink raw reply [flat|nested] 9+ messages in thread

Yes, when execute-extended-command was reimplemented in Lisp, the special code which produced "\370erase-buffer^M" was lost. Does the change below produce good results?
