Subject: [PATCH] This Patch replaces the default quit behavior with an dmenu
 prompt. Possible selections are (Quit DWM?) "yes", "no" and "restart". The
 additional confirmation can save your work from accidentally hitting the quit
 key by requiring two additional keystrokes (y/yes and RET). Additionally it
 allows for restarting / reloading dwm without ending the xsession and closing
 all open x windows. To abort press ESC or n/no and RET.
