Fix a bug with channels

When using IO operations from within a file, the channel would get
overriden before pushing a filename to the appropriate vector (op, ep,
or both). This is because Rune::Continue is used for newlines, and was
resetting the channel to None, before the push operation. Rune::Continue
is now broken out into its own match clause, that doesn't set the
channel before calling verse.add().
