Submitted by:	Steve Loughran <steve_l@iseran.com>

I've modified Steve's original submission to ensure quiet and
failonerror don't get set to true at the same time - also fixed the
logging a little as messages about failures to delete a file would go
to verbose logging or swallowed inconsistently in quiet mode.
