Title: Fix issue with multiline captions not being wrapped in text versions

While working on my current PPing project I ran into an issue where long lines within a multiline caption were not being wrapped in the text versions. I'm not sure if this behavior was intentional, but I can't think of a case where wrapping here would be an issue. This change adds line wrap to multiline captions.

Below is the ppgen code that illustrates the problem:
