[Vincent Ladeuil]

Fix python-2.7.6 test failures.

python 2.7.6 introduced a minor incompatible change in the email module. Some tests were relying on as_string() to get a representation of the email message. A final new line is now appended there...

A bug has also been fixed in python 2.7.6 ntpath.py module and some of our tests runs on all platforms and needed to be fixed.

None of those changes affect bzr itself, only its tests.

This has been tested on trusty and saucy to make sure the tests pass for all python versions.

Thanks for running this down. It looks good to me. I ran the test suite on Debian sid for good measure as it had been failing there as well. All tests were successful.

review: Approve

Thanks !

2.7.6 there too according to rmadison, so expected.

Great.
