could we do this maybe only when generateSpans is true?

  fileInfo = generateSpans ? ... : null;

that would match how we ignored the text entirely before if generateSpans was
false. It seems that all uses of fileInfo are guarded by that check as well.
Tests should just pass, if it's not easy to fix that, then let's add a TODO
about it here.

Done.

It turns out this made a test fail, so I changed it back and added a TODO.
