Well, it's behaving as documented, but what this means is we need to be
very wary of what contexts we can use .SECONDARY in. I'd just as soon
try to avoid using it at all --- my example with hand-edited gram.c
points out that even rather short dependency chains can have unexpected
misbehaviors if the intermediate files are marked .SECONDARY.

It was an experiment, nothing more; or at least that's how I saw it.
