The design and rationale looks better. The Crockford version is  
ill-defined in the sense that you can't recover the exact input string  
length in some cases; by example both "\x00"*4 and "\x00"*5 share the same  
encoding.
base-64 encoding, by example, uses '=' as pad bytes at the end to avoid  
this problem.
