open_by_handle test is covering more and more cases, thanks! OTOH, it's
getting more and more complicated :) Everytime I start looking at
open_by_handle tests/patches I need some time to get familiar with it
again, so the review process might be slow..

But from a quick scan, I think it's time to stop adding new sub-tests to
existing tests (maybe we should have done this since last time we added
new sub-tests to generic/467), because generic/467 is getting more
complex too and makes review harder. Perhaps we can factor out some
helper functions from generic/467 to common helpers and use them in new
tests.

OK, I'll see after reviewing all the tests.

Agreed.
