Let's take a one-question bug-or-feature quiz:
In isearch, when you type in a capital letter, isearch becomes
case-sensitive. However, when you delete the letter, the search
*remains* case-sensitive. In fact, there is no way to make it
case-insensitive without exiting and reentering the search.
Bug or feature?
I think it's a bug, and I intend to fix it. However, sufficient
number of people claiming it's a feature will convince me otherwise
(not to mention a veto of a member of the review board.)
FSF Emacs behaves the way I want to make XEmacs behave.
I vote bug. I cannot comprehend why anyone would call this a desirable
feature. It's totally nonintuitive.
(otoh, a key-binding to make the search case-sensitive _without_
having to type an uppercase letter would be nice ;-) M-c or something?
I think C-s is already taken in isearch-mode-map :-)
The above are my opinions,
and my opinions only.
