emacs -Q
M-x customize-option delete-old-versions
Value Menu: Leave
State: Revert This Session's Customization
The State is now back to STANDARD, which is correct.
In the State menu, this item is not dimmed, but should be, since there
should be no backup value different from the original value (Ask): Set
to Backup Value.
Choose Set to Backup Value anyway. The State now shows "SET for current
session only, which is incorrect (at best misleading).
The State menu now shows items Set to Backup Value and Revert This
Session's Customization, both of which are incorrect and misleading.
(The current value is the standard value, and we reverted to it.
Choose Revert This Session's Customization anyway.
State now says CHANGED outside Customize, which is 100% wrong. And the
State menu shows Undo Edits, Revert This Session's Customization, and
Set to Backup Value, all of which are wrong (and confusing).
Choose Undo Edits anyway. It has no visible effect - State and its menu
stay the same. Again, confusing.
Choose Set to Backup Value anyway.
State now says SET for current session only, which is (still) wrong.
And the same menu items are available, except Undo Edits. Choosing Set
to Backup Value again has no visible effect. Choosing Revert This
Session's Customization has the same incorrect effect as before (adds
Undo Edits to the menu and changes State to CHANGED outside Customize.
This is a confusing mess.
Without emacs -Q it is even more confusing, with Reset to Saved added to
the mix.
One thing that is not clear in the behavior is that Set to Backup Value
seems sometimes to be available without Reset to Saved (even without
emacs -Q). If you have made changes to the value that have not been
saved, then I would think that Reset to Saved would always be available
(until you choose it or you save).

Would it make sense to guard against backing up a value, if it's the
same as the new one? That way, Set to Backup Value would be disabled in
this situation.

I think this is a bug in `custom-variable-state': the first cond clause
doesn't check if value is equal to the standard-value, so it just
returns 'set. It should check for it and return the correct state.

Doing the two fixes above will fix this...

...But this message can still appear when it shouldn't:
emacs -Q
M-x customize-option RET delete-old-versions
Set the variable to Delete, for the current session.
Set to Backup Value, to bring back the standard value of
delete-old-versions.
Then Revert This Session's Customization.
This is a bug in `custom-variable-reset-saved': it is not resetting the
'variable-comment property of the variable when there is no saved-value,
and that confuses `custom-variable-state'.

I think this is just a consequence of the above three bugs. IOW, no new
bug here.
I'm not sure how to proceed here: should I send different patches for
the bugs, or put the fixes altogether in one patch?

Some other projects emphasize smaller and logically self-contained
patches. Here, the preference definitely seems to be towards making
bigger patches rather than many small ones. But I'm not aware of any
strict policy in this regard; it seems to be mostly at your own
discretion.
Someone will correct me if I'm wrong, but my take is this:
It's really up to what you feel makes more sense: if they are closely
related, you might prefer sending them in one patch; otherwise, it might
be better to send the changes in separate patches.
(My personal preference is to avoid bundling unrelated changes.
But I don't always work like that in Emacs.)

Hello Stefan,
Thanks for your answer.
I went with a single patch. If after seeing the patch someone feels it
should be split, just let me know.
Please review, and thanks.

Subject: [PATCH] Make State button interaction less confusing (Bug#12864)
* lisp/cus-edit.el (custom-variable-current-value): New function.
(custom-variable-backup-value): Use it.
(custom-variable-set, custom-variable-mark-to-reset-standard): Check
that old value is different than the new one. If it is, make a
backup. This way, we avoid offering the Set to Backup Value
unnecesarily.
(custom-variable-reset-saved): Reset the variable-comment property for
the variable, to help custom-variable-state be more correct. Also
check if we should backup old value.
(custom-variable-state): If a variable was set to the standard value,
say its state is standard rather than set, which is more correct.
Getting the right variable state is important for menu options to be
enabled/disabled, and for displaying the right message to the user.

I've been using Customize with this patch, without noticing any
trouble. I hope someone can review it soon.

Skimming it, it looks fine to me, so I've pushed it to the trunk.
And if there's any more outstanding patches of yours that has fallen
between the cracks, please do ping the relevant bug reports.

I think I've run out of those, unfortunately. All I have is some tests
that demonstrate the problem in Bug#21355, but I haven't worked in a fix
yet.

Thanks for working on this, Mauro.
I haven't checked the fix, but I'm sure it's good.
