I agree, and in fact I regard this as a feature (which automake has been known
to use in its own build system for some time).

But I see (with a simple "grep 'test -d' tests/*" command) that this behaviour
wasn't covered by our testsuite.  I've thus added a new test to ensure we don't
unwittingly break this feature (see attached patch, pushed to maint).

Thanks,
