Re: [rfa/testsuite/mi] Recognize a few incorrect outputs

The patch is fine.

Just to answer your previous question regarding Andrew's suggestion:

The text that identify the tests must be the same on both fail and pass.
However, a <reason> for the fail is allowed between parenthesis at the
end of ther string. The test comparison scripts are supposed to ignore
that part for test identification purposes.

The most used example of the aboce is the string "(timeout)".

Thanks for the patch. And thanks Andrew for the help with this one.

Regards,
Fernando
