No, "show escape" gives an indirect answer (if it isn't mate).

"show moves" should list legal moves.

The code has such tests, but they just don't have simple calls from the
text/xboard modes.

The format of the "show" command output is arbitary, in that it isn't
defined by the xboard protocol. If interchangable engines are important
to you, I suggest the Yahoo chess engines list is a good place to raise
such issues.
