In interactive calls, behave case-sensitively if the given char is an upper-case character. Same for zap-up-to-char (Bug#54804). This is analog to what the user-level incremental search feature does. * lisp/misc.el (zap-up-to-char): Add an optional arg INTERACTIVE. Perform a case-sensitive search when INTERACTIVE is non-nil and CHAR is an upper-case character. * lisp/simple.el (zap-to-char): Same. * etc/NEWS (Editing Changes in Emacs 29.1): Announce this change. * test/lisp/misc-tests.el (misc-test-zap-up-to-char): Add test cases. * test/lisp/simple-tests.el (with-zap-to-char-test): Add helper macro. (simple-tests-zap-to-char): Add a test.
