2021-04-22 Peter Lane

	* src/sanitize.lisp:

	Fixes issue 22 - sanitize mis-formats numbers
	The sanitize function converts numbers (actually, all non-strings,
	non-lists) to a string (using to-s) before they get to the format
	control string, and to-s uses the ~a directive. This means the control
	string provided to format-wish cannot use numeric directives.
	This fix adds a method to handle numbers by passing them back
	unchanged
	for formatting by the format-wish control string.
