-The Ghostscript internal operator .rsdparams wasn't checking the number or
-type of the operands it was being passed. Do so.

-Subject: [PATCH] Bug 697846: revision to commit 4f83478c88 (.eqproc)
-
-When using the "DELAYBIND" feature, it turns out that .eqproc can be called with
-parameters that are not both procedures. In this case, it turns out, the
-expectation is for the operator to return 'false', rather than throw an error.
