+Subject: [PATCH] add `-dy` flag for dynamic menu updating
+
+`-dy` flag makes dmenu run the command given to it whenever input is
+changed with the current input as the last argument and update the
+option list according to the output of that command.
+
+Based on dynamic options patch by ttmx <[email protected]>.
+Adds proper quoting of the given command.
+Adds option to man file documentation.
