Migrated issue, originally created by Mickey (@mickey)
This issue only exists if you're running alembic from the commandline in a pseudo-terminal, such as Emacs's shell.
File util.py line 23 calls fcntl.ioctl which unpacks the number 0 into TERMWIDTH, but that is invalid according to the textwrap module, resulting in the aforementioned exception.
The fix is to assign None to TERMWIDTH (if 0) or replace the if check on line 182.
