Tab completion doesn't recognize line breaks in usage strings

[con-f-use]

The follwing docstring is perfectly parsed by docopt:

Usage:
  example.py ( cmd1 | cmd2 |
     cmd3 )

But docopt_wortlist has problems in bash shell

confus@confusion:~$ example.py Expected pattern but reached end of usage pattern.

Seems like a bug in docopt.rs proper. I wonder if that type of syntax should even be allowed by Docopt.

[con-f-use]

I don't know if it "should", but it is. My example is parsed correctly and cmd3 is recognized as a command by pythonic docopt. Multiline usage strings are allowed.
See:
docopt/docopt#130

Btw. depending on whether the | character is before or after the linebreak I get another error message:

confus@confusion:~$ example.py Unclosed group. Expected ')'.
