Preprocessor: fix `undef` and redefinition (#204)
* Preprocessor: fix `undef` and redefinition
The logic for `undef` directives was failing to suppress macro expansion when reading the name to un-define, and so it wasn't actually working at all. We didn't notice this because we didn't have a test case, and users hadn't tried it.
The logic for `define` had a similar bug, which meant that any attempt to define an already-defined macro would fail with a cryptic error, rather than raising the intended warning.
Test cases have been added for both issues, along with the fixes.
* fixup: add expected output for tests added
