Mainly we also needed to trim around comment tags, but also there were a bunch
of tricky edge cases that were only partially addressed. This is some edgy
business!
The specs tests assumes an implementation will silently ignore invalid delims.
I think that's a bad idea, so I throw an exception on invalid delims. So I just
ignore those "tests".
The groups with failing tests are currently commented out (everything except
interpolation). The main reason for failures are due to the requirement that
standalone lines that contain nothing but whitespace be stripped from the
output.
