to add additional escapes, though at the cost of an unusual comment

enough to be fairly obvious.
// comments would mean URLs in captions would require escaping. Most
formats that use that style of comments are programming languages,
which don't have loose URLs outside of strings.

I don't think getCueAsHTML helps an editor (since it's one-way); an
editor will probably need to have its own parser, which isn't a big
deal. As long as there's support for comments in the file format, so
people don't need to make up a "working" file format just to add them,
that's enough; such a parser can handle comments however it wants.
