Tolerate output spew generated by the readline library on some machines

It seems that on some machine configurations the readline library has the bad idea of spewing some control characters to stdout. This causes failures in any test that is reading from the command line, which currently only happens in debugger tests. Possibly this behavior shows up on the continuous build machines, so we'll make the expected output provide for this variation, just in case.
