step 13: copypasta in "the character at position is not a U+003A COLON

From context, it seems that the "not" shouldn't be there.

It seems to me that the parsing of WebVTT timestamps is more convoluted than it needs to be, and that the reason is that hours can be any number of digits. In SRT it is exactly 2 and I think just going with that would be simpler. Allowing an arbitrary number of digits just makes parsing more complex and forces implementors to handle overflow in timestamps like 99999999999999999999999999:00:00.000 and using greater precision than really necessary.

There's also extra logic thrown in to not allow single-digit minutes in step 13.1.

I'd prefer exactly 2 digits for hours, limiting WebVTT to use with video files of duration shorter than 100 hours, which is hardly a practical problem.

Opened a separate bug for the issue of 2-digit hours:

Checked in as WHATWG revision r5825.
Check-in comment: VTT: copypasta that made the parsing of timestamps fail if
they had an hour component.
