Issue #27829: regrtest -W displays stderr if env changed

vstinner · vstinner · commit bd2ffa502212 · 2016-09-23T11:13:53.000+02:00
regrtest -W hides output if a test pass, but also when env changed and so the
env changed warning is hidden. So it's hard to debug. With this change, stderr
is now always displayed when a test doesn't pass.
