Yes -- I've pushed a fix.

Beware, though, that the document-building phase of `raco setup' uses
the ".zo" file for a document to determine whether the document should
be rebuilt. If you omit the document from compilation, then `raco
setup' will assume that the document needs to be rebuilt every time.
