typing: correct the signature of error.CommandError
There's a place in `mercurial.dispatch._parse()` that passes None if a parse
error happens before the command can be parsed out, and casting the error to
bytes works fine because the command and message fields are apparently ignored.
Likewise, TortoiseHg similarly passes None for the same reason.

""" List-valued configuration keys have an ad-hoc microsyntax.

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.
