You actually can't. Sorry. :-)

The check to be done should be "or" as your original test was catching
single entries as well (as in just with release-date or just with eol-
date).

This comment still aplies.

This, doesn't. Sorry. :-)

So, in the end, my suggestion is to add to this patches something like:
```

If I get your ack on this, I can just squash the patch into yours and
push without the need of a v2.
