	* g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
	position set is provided, we compute one in order to reduce the maximum
	length of the keys.  This computation first selects a character
	position between 1 and the minimum length of the keys in order to
	avoid reducing one of the keys to an empty string.
	(Initialize, Compute): When the ratio V to K is too low, the algorithm
	does not converge. The initialization procedure now comes with a
	maximum number of iterations such that when exceeded, an exception is
	raised in Compute. The user can initialize this ratio to another value
	and try again
	Reformating and updated headers.
