Avoid throwing an error with misc-user events in isearch-pre-command-hook. lisp/ChangeLog addition: 2013-08-05 Aidan Kehoe <kehoea@parhasard.net> * isearch-mode.el (isearch-pre-command-hook): If this function is called and (this-command-keys) contains misc-user events, #'key-binding throws an error. Eddie Corns and Alex Belits describe this happening in tracker issue 336, and we can avoid this by catching the error and handling the misc-user event in the same way that #'dispatch-event does. I haven't reproduced the actual error they describe, and welcome testing to make sure it's gone. Thank you Eddie, thank you Alex!
