Subject: [PATCH] Add t/curse, a multi-level dependency build that really
 aggravates redo.

...because it seems my locking isn't very good.  It exposes annoying
problems involving rebuilding the same files more than once, screwing up
stamp files with redo -j, and being unnecessarily slow when checking
dependencies.  So it's a pretty good test considering how simple it is.

Didn't add it to t/all.do yet, because it would fail.
