Enable Case sensitive when specifying an upper case letter #88
Description
I have a suggestion: make search case sensitive if the user specifies an upper case letter.
I believe this is consistent with how Emacs manages searching and case:
An upper-case letter anywhere in the incremental search string makes the search case-sensitive.
Of course, this should happen only in case ace-jump is set to be case insensitive (e.g. (setq ace-jump-mode-case-fold nil)); with (setq ace-jump-mode-case-fold t) then the letter should match exactly, including case.
