RE: [PATCH] to improve case management in search routines.

In addition to the bug Hrvoje fixed in isearch, I'd like to propose the following patch to generalize the behavior of isearch (which is the Right One) to other searches as well. The point is that when calling interactively a routine that leads to a search (even basic, non-incremetal, non-regexp ones), the introduction of an uppercase character in the search srting should switch back to case-sensitive search, regardless of the value of case-fold-search (but still taking search-caps-disable-folding). isearch currently behaves this way, but we'd like to see other functions (like zap-to-char) follow this rule too. The following patch generalizes the use of isearch-no-upper-case and with-caps-disable-folding (moving them away from isearch.el), and corrects the behavior of the `zap-*-to-char' functions. I'm likely to modify other functions along with the same lines in the future as they come to my mind. One important point: there are 2 interface changes in this patch: the routine isearch-no-upper-case-p is moved away from isearch.el in order to be used anywhere else, so the isearch- prefixe is removed. The other one is one more argument (regexp-flag) to the macro with-caps-disable-folding, which is moved away from isearch too. I think we can afford those changes: they lead to only 2 other modifications in the core lisp packages, and none of the packages I have installed (almost all of them) use those functions. _this patch must be applied on top of hrvoje's previous one_ (<kigyarb68yb.fsf(a)jagor.srce.hr>)
