[Flac-dev] --until decodes rest of file?

Hi
I'm having a seemingly odd problem with flac 1.1.0: when I decode a
large (CD size) flac file, using --skip and --until to extract a single
track, flac appears to continue to decode until it reaches the end of
the file:
donald at klatch:~/arch/loveovergold$ time flac -d -o - --until=+1048576 data.flac > /dev/null

As you can see, starting at the beginning of the file always takes about
the same amount of time, and starting later still takes a reasonable
amount of time to decode 1Msamples (~23s).
I'm guessing this is a bug :-)
