Apologies.  The bug report was from Emacs 26.  I see
now that the doc string was improved since then to
what you quote.

In Emacs 26, it says only this:

 Each element of this list looks like

     (REGEXP COMMAND...)

 where each COMMAND can either be a string or a Lisp
 expression that evaluates to a string.

Feel free to close the bug.  Thx.
