+	Request that surface is pinned.
+
+	This is only a request that the window should be pinned.
+	The compositor may choose to ignore this request. The client should
+	listen to set_pinned events to determine if the window was
+	pinned or not. If trusted flag is non-zero, the app can prevent users
+        from exiting the pinned mode.

indented the same way as other descriptions. mix of tabs and space..
