cuebreakpoints doesn't like cuefiles generated by metaflac

[siebenstreich]

On a flac file with embedded cue sheet, the command

metaflac --export-cuesheet-to=[cuefile] [flacfile]

creates a cue-file with the first line

FILE "[flacfile]" FLAC

Running cuebreakpoints on the generated cue-file, the first messages I get is bad character 'F' bad character 'L' bad character 'A' bad character 'C' 2: syntax error

So cuebreakpoints doesn't like the keyword 'FLAC' in the first line, I have to manually change it to 'WAVE'. It would like to suggest to make cuebreakpoints less restrictive in this place to allow to directly handle such auto-created cue files.
