I have bound M-k to bury-buffer.

Typing C-h t to see the tutorial shows me these 2 lines (and lots of
other, expected text):

        M-k          Kill to the end of the current sentence
  ** M-k has been rebound, but you can use  instead [More] **

The bug I'm reporting is that "you can use  instead" doesn't mean
anything.  It looks like an empty string has been inserted there.

kill-sentence isn't bound anywhere.  Clicking the '[More]' link shows

Here is a patch for that. It also takes care of the problem when a key was rebound to nil:
