bug#56106: 'C-h k' defeats command substitution

Command substitution does not work with 'C-h k'.:

0. emacs -Q
1. C-x r l
2. C-h k m

I now see a buffer with this text:

  Mark bookmark on this line to be displayed by
\<bookmark-bmenu-mode-map>\[bookmark-bmenu-select].

I expect to see:

  Mark bookmark on this line to be displayed by v.

This works as expected in Emacs 27.2.  I suspect this is a recent
regression.

Yup.  Now fixed on the trunk.
