[vlc-devel] [PATCH] oldrc: add relative seek support

[Mike Frysinger]

Most of the time, I want to seek short bursts forward and back, not to
absolute positions.  So add support to the current "seek" function to
do just this.  Prefixing the time with a "+" or "-" will make the seek
relative accordingly.
