//// extended terminology escape handling goes in here
//
// this is where escapes get handled *IF* the termpty layer needs to interpret
// them itself for some reason. if it returns EINA_FALSE, it means the escape
// is to be passed onto termio layer as a callback and handled there after
// this code. an extended escape may be handled in here exclusively (return
// EINA_TRUE), handled here first, then in termio (EINA_FALSE return) or not
// handled here at all and just passed to termio to figure it out (return
// EINA_FALSE).
//
// command strings like like this:
//   axBLAHBLAH
// where 'a' is the major opcode char.
// and 'x' is the minor opcode char.
// and 'BLAHBLAH' is an optional data payload string
