[issue11887] unittest fails on comparing str with bytes if python has the -bb option

[Nick Coghlan]

Nick Coghlan <ncoghlan at gmail.com> added the comment:

I'm OK with that - I'd actually suggest explicitly *emitting* a warning when the error is suppressed under -bb, as Ezio is right that even tests should be keeping their bytes/str separation straight. I don't like completely suppressing warnings/errors when a user has explicitly requested them.

I'd also be OK with a filtering approach that coerced the handling to "default" rather than "ignore" (although that require a bit more work to keep unittest from acting as though -b was always set on the command line).
