Bug found. It was caused by the OpenCL progress indicator. It made the
guesses line look something like this (where ^H is backspace):

\^H|^H/^H-^H\^H|^H/^H-^H\^H|^H/^H-^Hguesses: ...

...and Test Suite could not parse that. So we now remove everything up
to the last backspace. This was very hard to nail because I never saw
the darn thing in my debugging - but the length of the line did not
match what I saw.
