Subject: [RFC] player: "cue prev" reliably hits previous cue breakpoint
Date: Mon, 11 Apr 2016 02:27:43 +0000	[thread overview]
Message-ID: <20160411022743.GA22090@dcvr.yhbt.net> (raw)

Seeking around a track should not be done relative to
a previous seek, but should rather be analogous to the
"tl prev" command to skip around the tracklist.

I'm not sure what drugs I was on when I originally wrote
this original version, but I'm fairly certain this is a
bugfix and not intentional behavior.

  Thoughts?  I'm _pretty_ sure this is the right thing to do;
  will think about it for a bit...
