This would make sense if the two operations did the same thing. I don't think they do; I think the Ctrl-Shift-X key sequence causes konsole to send SIGWINCH. >> I understand how it may look confusing, but I don't think the term has >> much option here.

And I press Ctrl-Shift-X in bash only. :) There is a better explanation in one of the threads I referenced in my previous message, but here's the short story: readline has always set SIGWINCH to restart system calls. It would redraw the prompt upon receipt of a SIGWINCH in previous versions because it (incorrectly) executed that code in a signal handler context. Cleaning up the code so it didn't try to execute arbitrary code in signal handlers was one of the big changes between bash-4.2/readline-6.2 and bash-4.3/readline-6.3. > Also, is there somewhere some real revision control system with bash sources? > http://git.savannah.gnu.org/cgit/bash.git appears to be incomplete: "git > bisect" shows that the problem is in > http://git.savannah.gnu.org/cgit/bash.git/commit/?id=ac50fbac377e32b98d2de396f016ea81e8ee9961 > , but this is a huge commit. Where can I download more detailed history? Try looking at the devel branch.
