"." ends a multi-line header.  A blank line, when not contained within a
multiline header, ends header processing.  (Additionally, for error
handling, header processing is also ended by a line containing "-->", but
only if it's not within a multiline header or a valid single-line header.
It's easy to distinguish "00:01.000 --> 00:02.000" from "Style: value", as
long as you don't allow headers to start with a digit.)
