I'd like to keep the QMP output a prettified version of the plaintext
output, and not have it omit things. You can make the case for changing
that behavior in a separate patch.

Feel free to enhance the test suite later to understand all the types of
commands and replies and scrub them automatically. For now, specifying
the filters matches behavior in much of the rest of the test suite and I
am not motivated to fix it.
