Date: Sat, 24 Jun 2017 07:58:47 +0200

Hello,

Evaluate this:

(defun test (arg)
  (interactive (list (read-from-minibuffer "Input: ")))
  (message "%S" (cons this-command (this-command-keys)))
  arg)

(global-set-key [f12] #'test)

where f12 stands for some random key sequence.

Hit f12 and give any input.  I get the following message:

(test . "^M")

I would expect (test . f12).

Obviously, `this-command-keys' returns the key confirming the input
instead of the key that has invoked the command.  This contradicts the
descriptions in the documentation (docstring and manual).  The docs only
mention an exception when a command calls `read-key-sequence', but this
is not the case here.  FWIW, I would prefer fixing this over changing
the docs.


Thanks,

Michael.
