I blamed my way through the history, and this is the source of that
part of the line:
http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=ec0bd3b93a2fa3384d645d1d4b70a3226782fe75

Doesn't seem to be much of an explanation why this was chosen, so
there may be no particular reason for this over your suggestion, or it
was just not documented.
