Gnus/5.13 (Gnus v5.13) Emacs/24.0.90 (gnu/linux) |
In GNU Emacs 24.0.90.2 (i686-suse-linux-gnu, GTK+ Version 2.22.1) of
2011-10-03 on escher
Windowing system distributor `The X.Org Foundation', version 11.0.10903000
configured using `configure '--without-toolkit-scroll-bars' 'CFLAGS=-g''
1. emacs -Q
2. M-x customize-option RET completion-category-overrides RET
=> The state says: "STANDARD. (mismatch)". In addition, the only widget
is an editable field, containing the default value as a Lisp sexp; but
according to the defcustom code there should be an alist widget
containing various other widgets to support customization.
These problems are due to a typo and an oversight, corrected in the
patches below.
Aside from the bugs, I think the Customize interface here can be
improved from the point of view of a user ignorant of Lisp by using
helpful tags instead of the default widget labels "Set", "Cons-cell" and
so on. The second patch below is an attempt to do this. (This patch
also incorporates the fixes of the first patch, so if you like the tags,
only this patch should be applied, and if you don't, only the first
patch.)
Here's the straight bugfix:

Oops, indeed, I didn't copy&paste properly :-(

I've installed this second patch, thank you.
I don't like much the "Select a foo from the menu" thingies, but left
them there. I'll let someone more knowledgeable about Customize (and/or
with stronger UI tastes) figure out whether they need to be changed
and how.
