Thanks, I fixed the doc string.

What is this about?  A left-over of editing some other message?

[Message part 3 (message/rfc822, inline)]

The description of `imenu-generic-expression' is incomplete.  It does
not specify the case where argument REGEXP is a function.

The doc string describes this use case this way:

REGEXP may also be a function, called without arguments.  It is expected
to search backwards.  It must return true and set 'match-data' if it
finds another element.

Unfortunately, the last sentence there is unclear.  The function does
not "find another element".  It finds a definition construct in the
buffer, and it sets match data for it.  It does not construct or "find"
an element of the list that is the variable value.

But this bug report is about the missing description of the
REGEXP-as-function case.
