Subject: Error in auto-revert-buffers: Wrong type argument
Date: Wed, 13 Feb 2019 13:00:43 -0600

Hi Michael -

The fix for this bug seems to cause issues if default-directory is nil
for any buffer. In particular, you get a wrong type argument where
auto-revert-buffers is expecting a string instead of nil.

This change fixes the issue for me:

Thanks,
Alex
