assertThat unconditionally prints matchee on mismatch

[James Westby]

Hi,

In some cases printing the whole matchee is not helpful to the developer using
testtools.

With the support for adding details from mismatches it is possible to provide the
full matchee to the developer when the majority isn't going to be that useful.

For soupmatchers I want to get away from printing the whole HTML document,
because it could be huge and only a small part of it be useful.

I would suggest that the Mismatch was able to format the matchee for display,
giving essentially more control to the matcher, rather than assuming one size
fits all.

Thanks,

James

Hmm, something should be tweaked, thats for sure. However, matcher
composition implies Mismatch composition,and I don't see printing full
context from there to make sense.

This is a genuine issue, even if it might be tricky to solve well. I've rephrased to drop the "should" and marked as Triaged rather than incomplete.
