Behdad Esfahbod 75504a5048 Allow serializing buffer with output-buffer being used 
Ie, don't call get_positions() if positions are not
requested for serialization.

Behdad Esfahbod 7627100f42 Mark unsigned integer literals with the u suffix 
Simplifies hb_in_range() calls as the type can be inferred.
The rest is obsessiveness, I admit.
