I have an offlineimap configuration that retrieves authentication material
from .netrc.  This configuration stopped working with the most recent update
in testing.  See below for the offlineimap command output.  Note that
nothing has changed with the server and if I remove ~/.netrc and copy &
paste the values from it to the interactive offlineimap password prompt,
authentication is successful.  The problem appears specific to .netrc.
