ccwl: Raise exceptions on output syntax errors.
* ccwl/ccwl.scm (output): Raise &ccwl-violation conditions on syntax
errors.
* tests/ccwl.scm (output): New function.
("output, when passed more than one positional argument, must raise a
&ccwl-violation condition", "output, when passed an unrecognized
keyword, must raise a &ccwl-violation condition", "output, when passed
multiple arguments to a unary keyword, must raise a &ccwl-violation
condition"): New tests.
