- Version bump to 1.50 PR2.
    Added --noprompt, --recurse and --summarize options
    Now sorts duplicates (old to new) for consistent order when listing or
        deleting duplicate files.
    Now tests for early matching of files, which should help speed up the
        matching process when large files are involved.
    Added warning whenever a file cannot be deleted.
    Fixed bug where some files would not be closed after failure.
    Fixed bug where confirmmatch() function wouldn't always deal properly with
        zero-length files.
    Fixed bug where progress indicator would not be cleared when no files were
        found.
