If you do:
1) C-h f display-buffer <RET>
2) Click on pop-up-frames
3) Click on customize
4) Click on the [back] button in the Help buffer
you get the error:
apply: Symbol's function definition is void: nil
This is because help-xref-stack has been set back to nil by clicking on
customize:
In help-mode.el:
(define-button-type 'help-customize-face
:supertype 'help-xref
'help-function (lambda (v)
(if help-xref-stack
(pop help-xref-stack))
(customize-face v))
'help-echo (purecopy "mouse-2, RET: customize face"))
The error goes away if help-xref-stack is not popped but the ChangeLog says:
2000-05-09 Dave Love <fx@gnu.org>
Changes mostly following Richard Sharman <rsharman@wave.home.com>.
* help.el (describe-variable): Have customize button pop the
help-xref stack when invoked.
Does anybody know why this is necessary?
Nick
