0.8.10.19:
	Fix floating point read/print consistency, with a slightly
	tidied up version of Burger and Dybvig from the one CSR posted
	to sbcl-devel ca. end 2004-04.
	... no more recursion, yay!
	... still two versions of float printing algorithms
	... test case
	... fix the reader too.  (The original workaround was probably
		a CMUCLism from having :underflow traps enabled; since
		SBCL has never been distributed with underflow traps,
		we can remove the workaround).
	Log all remaining undisputed bugs from Bruno Haible.
