Inline comments unsupported

Code like this:

self.assertEqual(
    # Comment about a
    a,
    # Comment about b
    b,
)

Currently chokes the fixer parser, so we choose to skip them.

If we didn't skip them, it would convert to this unparseable code

assert \
    # Comment about a
    a \
    # Comment about b
    b
