RunResult.__repr__ should represent name for ret #4901
Description
The following:
r = testdir.runpytest_subprocess(p)
> assert r.ret == 0
E assert 2 == 0
E + where 2 = <RunResult ret=2 len(stdout.lines)=16 len(stderr.lines)=1 duration=0.69s>.ret
would read better as:
r = testdir.runpytest_subprocess(p)
> assert r.ret == 0
E assert 2 == 0
E + where 2 = <RunResult ret=EXIT_INTERRUPTED len(stdout.lines)=16 len(stderr.lines)=1 duration=0.69s>.ret
I.e. it should display "EXIT_INTERRUPTED" (or similar) instead of "2".
