pytype: add type information for `annotateresult.lines`

This seems to appease a confused pytype.

"""
List-valued configuration keys have an ad-hoc microsyntax. From `hg help config`:

> List values are separated by whitespace or comma, except when values are
> placed in double quotation marks:
>
>     allow_read = "John Doe, PhD", brian, betty
>
> Quotation marks can be escaped by prefixing them with a backslash. Only
> quotation marks at the beginning of a word is counted as a quotation
> (e.g., ``foo"bar baz`` is the list of ``foo"bar`` and ``baz``).

That help documentation is fairly light on details, the actual parser has many
other edge cases. This test tries to cover them.
