Mismatching posix chars when using colors

[stof]

Looking at the outpyt, it seems like some POSIX color control chars are mismatching for the testsuite summary (OK (18 tests, 40 assertions)) and the code coverage report summary. the green background color fills the next (empty) line too.

and when running the same testsuite on travis, these 2 parts of the output disappear, which I suspect is related to a stricter parsing of the output. You can see it on https://travis-ci.org/Incenteev/IncenteevTranslationCheckerBundle/jobs/8498973

Sounds like your terminal emulator doesn't support background color erase. I think it's a similar situation for travis.

For the record, I wouldn't mind removing the background color erase sequences so that our output will look better on more emulators (especially travis). The only thing that would change is the background color wouldn't stretch to the end of the window like it does here:

If @sebastianbergmann agrees, I should have time to do this in the next couple of days.

Sure, go ahead.

What about sebastianbergmann/php-code-coverage#174?

[whatthejeff]

I should have time for that one later today.

Alright, this should be better now. I've included some before and after screenshots below. Feedback is appreciated:

Also, here's an example of what code coverage looks like on travis now: https://travis-ci.org/sebastianbergmann/php-code-coverage/jobs/8926881
