	* spell.lisp: KNOWN-EDITS2: bug fix

	* testing.lisp: *** empty log message ***

	* spell.lisp: bugfixes

	keep duplicates. This improves the speed of EDITS2 but the consing
	stays.
	Speed is almost the same.

	* spell.lisp: Added comment to DOEDITS.

	* testing.lisp: Moved test results to 'spell.lisp'.

	* spell.lisp: In order to reduce consing, macro DOEDITS was defined.
	Time is now comparable to Python.

	Can we do better? (EDITS2 "something") is 629 s with 22.6 MB consing. Python has a delay
	about a second only!

	* spell.lisp, testing.lisp, utils.lisp: New file.
