Eliminate funcalls, #'handle-pre-motion-command-current-command-is-motion 2010-01-20 Aidan Kehoe <kehoea@parhasard.net> * simple.el (handle-pre-motion-command-current-command-is-motion): This function is called a *lot*, make it faster, making keysyms-equal inline, calling #'characterp (which doesn't have a bytecode) much more rarely, and not throwing and catching. This won't make much difference in practice, but does eliminate losts of noise from profiling, e.g. at startup.
