feature request: auto-toggle case fold

[Lompik]

Is possible to have have case fold search activated (only for currently active search) on uppercase letter user input ? If I bother to to enter shoft+letter, most likely I want case fold on.

See avy-case-fold-search.

Ok so the feature seems there but it isnt working as expected I think. in hte case of avy-goto-word-1 with letter "J", down in avy--regex-candidates, the regex is \\bJ. But then this:

(not (string= regex (upcase regex)))

will compare \\BJ and \\bJ so it will always be non-nil thus matches ignore case.

But then inside avy--regex-candidates even if I use:

(let ((case-fold-search nil)

still isn't working. The docs says "Automatically becomes buffer-local when set." so wondering if this is related.

I don't see the problem, avy-goto-char with J will search only for J when avy-case-fold-search is nil, and for J and j when it's t. Works as expected.

I tested with emacs -Q and avy-goto-char works as expected but the actual problem is with avy-goto-word or any avy-* with a lowercase regex added to pattern. Basically the condition:

(not (string= regex (upcase regex)))

should be done on patterns not regexes. In the case of avy-goto-word, the regex is \\bJ , \\b for word boundary and J the pattern. (upcase regex) return \\BJ which is not equal to the original regex \\bJ. If it was done on the pattern then J (orginal) will match J (upcase).

Should be better now, have a look

works great. See #128
