* refs/heads/master: Fixed memory leak in xu_get_strprop. Prevent out of boundary write with configuration files in which too many quoted arguments are stored for other window managers. Allow configuring a percentage window size of the master window during htile/vtile actions. From Uwe Werler, with a few manpage tweaks. zap stray tabs Instead of using _NET_ACTIVE_WINDOW on restart, use the pointer location to determine what client to set active. Reduces a round trip for every window. Add support for SIGINT/SIGTERM. Simplify conditional construct. Trim event_mask to those that the root window actually needs. No need to lookup current client early; move to right before it is needed. Recommit 1.259, but now with TAILQ_FOREACH_SAFE. Revert previous. Causes a crash as reported by Tom Murphy. Simplify list markup. Plug two memory leaks. Also get rid of a variable that is no longer necessary. Remove ColormaskChange from event-mask since there's no event handler. Unrelated style fixes, consistency changes and sorting, appropriate dosage/removal of wrappers, simplification of name queue, client cycle joins other kb/mb bound functions.
