obsolete: use 2 argument form of enumerate()
The 2 argument form of enumerate was added in Python 2.6. This
change effectively reverts
10880c8aad85.
tests: remove special handling for undefined memoryview
'memoryview' was introduced in Python 2.7.
4adc090fa2fb added code
to filterpyflakes.py to ignore "undefined name 'memoryview'" pyflakes
warnings. Since we no longer support <Python 2.7, we can remove this
workaround.
encoding: remove workaround for locale.getpreferredencoding()
locale.getpreferredencoding() was buggy in OS X for Python <2.7.
Since we no longer support Python <2.7, we no longer need this
workaround.
This essentially reverts
2be70ca17311.
mail: remove code to support < Python 2.7
This code was added in
594b98846ce1. Since we no longer support
Python <2.7, it can be removed.
help: clarify that colons are allowed in fingerprints values
This was suggested by Lars Rohwedder in
issue5559.
sslutil: tweak the legacy [hostfingerprints] warning message
Lars Rohwedder noted in
issue5559 that the previous wording was
confusing. I agree.
