I know.  What I wrote was not a complaint about the past, it was a
suggestion for the future.  A single localized change doesn't yet
justify importing a large test suite.  But this later patch looks like
a beginning of a series of refactoring (is it?), hopefully followed by
more features, so I thought we should have a firm ground first.

Thanks.
