+## Awful N900 hacking.  The N900's keymapping is hopelessly broken: the
+## return key is bound to the KP_Enter keysym (and this can't be fixed
+## without breaking the desktop).  Mostly, stuff is fine except that when
+## terminal clients switch to application mode, they get the `fe' sequence
+## ^[OM instead of ^M, which they often don't deal with well.  Trap this
+## sequence here, and map it back to ^M.
