* 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.
