Nixpkgs switched to OfflineIMAP version 8 which means that Python 3 is
now used instead of Python 2. As a result, get_pass() now returns a
byte array instead of a string and the argument to get_pass() must be
a byte array too. See
https://github.com/OfflineIMAP/offlineimap3/issues/103.
This allows me to use offlineimap with passwordstore. I guess nobody
uses a newline in their password?
