Subject: 29.2.50; describe-function should support finding references
Date: Wed, 28 Feb 2024 12:31:13 -0500

In emacs-lisp-mode in an Emacs git checkout, M-? (xref-find-references)
nicely searches the load path for references to a symbol.

It would be neat if this feature could be accessed from
describe-function and describe-variable as well, perhaps by just hitting
M-? in the help buffer.

The feature may need to be redesigned somewhat, since it's currently
dependent on being run from a project; to use it from a
describe-function help buffer, we'd want to only search the load-path.
