+The code assumes that "kmous" capability is for X10 mouse reporting,
+so if an event for kmous happens it tries to decode it according to
+the X10 protocol.
+
+This breaks starting with ncurses 6.1 as the terminfo for xterm
+started using the SGR sequence for xterm in 6.1.
+
+This is a hacky, non-invasive patch which just assumes that the SGR
+protocol is used.
