Not quite sure what's wrong here.  foo:lines should get coerced into a list
type.

Your default value in the function signature should therefore be
keywords=(), rather than keywords=''.  But if you're passing a value in,
this shouldn't be a problem.

Watch out for using the name kw for a variable, since this is the standard
name for a dictionary of keyword arguments.
