The former is only set at configure which is a bit confusing, and I can't think of a reason to have both.

Change how whitespace in subtitles is handled.

2023-02-16T20:56:22Z

Previously we would discard any whitespace subtitle content we found. This had the side-effect of making a verification test fail (checking that at least one subtitle is in each reel; blank subtitles are often used to avoid this warning). Here we take any subtitle content, whitespace or not, inside a or node which I think is a little more correct.
