Decoding options bug

[jack461]

There seems to be a bug [chuck,1.3.5.2] in the option decoding when a filename begins with a digit:

$ chuck --dac:5 4-Main.ck
[chuck]: (CoreAudio) timeout waiting for sample rate update for device (4)...
[chuck]: cannot initialize audio device (use --silent/-s for non-realtime)
$

But this works:

$ chuck --dac:5 ./4-Main.ck
$

Not a big problem, of course, but that should be easy to fix. Regards.
