I agree, thanks for the suggestions. Just pushed the following two commits.

    src/flac/encode.c : Improve message when compression fails.
    As suggested by Brian Willoughby this is not an "ERROR" but a "FAILURE".
    Also list a couple of possible causes of this failure and remove the
    suggestion to contact the developers.

    src/flac/main.c : Change the default beahviour when compression fails.
    Previously the flac executable would return a non-zero exit code when the
    output file was bigger than the input file and this could be disabled with
    the --no-error-on-compression-fail option.
    New beaviour is to print the failure message but return a zero exit code
    in the above situation, and only return a non-zero exit code with the
    --error--on-compression-fail option. The --no-error-on-compression-fail
    command line option has been retained.
