Johnothan King a282ebc8fe Fix emacs backslash escaping behavior (#179) ... This commit fixes the following: 1. Emacs mode ignores --nobackslashctrl (re: 24598fed) when in reverse search. 2. When entering more than one backslash, emacs reverse search mode deletes multiple backslashes after pressing backspace once. Reproducer: $ set --emacs --nobackslashctrl $ <Ctrl+R> \\\\<Backspace> 3. Except when in reverse search, the backslash fails to escape a subsequent interrupt character (^C). Reproducer: $ set --emacs --backslashctrl $ teststring \<Ctrl+C> src/cmd/ksh93/edit/emacs.c: - Disable escaping backslashes in emacs reverse search if 'nobackslashctrl' is enabled. - Fix the buggy behavior of backslashes in emacs reverse search by processing backslashes in a loop. src/cmd/ksh93/tests/pty.sh: - Add regression tests. src/cmd/ksh93/sh.1: - Fix a minor documentation error (^C is the usual interrupt character, not ^?).
