Error when calling describe-variable/key/function() in help-fns+.el

Error when calling describe-variable/key/function() in help-fns+.el

[Nordlöw]

I get the following error:

Debugger entered--Lisp error: (void-function describe-simplify-lib-
file-name)
  describe-simplify-lib-file-name(nil)
  describe-variable(nil nil nil)
  call-interactively(describe-variable nil nil)

when I try to use describe-variable()

I searched for describe-simplify-lib-file-name in my emacs configs and
found it in only once in help-fns+.el.

Then I looked into lisp/Changelog and found the following entry that
mentions describe-simplify-lib-file-name(). I am using Emacs version
23.0.60.1.

	* help-fns.el (describe-simplify-lib-file-name)
	(find-source-lisp-file): Removed.
	(find-lisp-object-file-name): New function giving preference to
	files found via load-path instead of loaddefs.el.
	(describe-function-1): Use new function instead of the removed
	ones.  (Bugs #587, #669, #690)
	* faces.el (describe-face): Use find-lisp-object-file-name instead
	of describe-simplify-lib-file-name.

Thanks in advance,
Nordlöw

Hi Per,

This is the cost of living on the bleeding edge. ;-)

In my code (e.g. help-fns+.el), I don't yet support Emacs 23, which is still
unstable and not yet released.

To the extent I have time, however, I try to adapt my code to changes I notice
in Emacs 23. I don't yet have a Windows binary for any changes that were made on
9/01, and I probably won't have such until next month (thanks, Lennart!). And
Savannah seems to be down currently
(savannah.gnu.org/cgi-bin/viewcvs/emacs/emacs/lisp/), so I can't get to the
latest source code.

I've replaced `describe-simplify-lib-file-name' with
`find-lisp-object-file-name' if it's available. Dunno if that will suffice here.
Sorry for the inconvenience, and thanks for your report. Let me know if this
change does the trick.
