Function List->Formatted-String

Part of:

package metabang.utilities
( list->formatted-string < list > &optional < separator > < end-with > )

This is a convenience function for when the intracacies of format are just too much. It takes a list and returns a string formatted with delimiter&#39; between each sucessive element and ending with ends-with`. look in CLtL2, section 22.3.7.2 for the full deal.
