Remove gcc (4.0.x) warning about uninitialized value by explicitly setting

the sentinel value in the main function, rather than the helper. This
function could possibly do with an early-out if any of the helper calls ends
up with a len of 0, but I doubt it really matters (how common are malformed
hangul syllables, really?)
