Comment:
Not quite. {{{a3920181}}} is a partial fix that solves a more serious
problem when {{{-copyts}}} or {{{-c copy}}} are used (wherein the seek
operation previously would have no effect, and now proceeds somewhat
slowly). I have a patch on the ML that fixes this slow-seeking issue
caused by failure to read the second SeekHead, but it hasn't been applied
yet because we need to double-check some edge cases first.
Oh, and a3920181 may speed up seeking in these files, but not by as much
as reading the second SeekHead would.
