1881a1a by Guy Harris (guy@xxxxxxxxxxxx):

    Back up to the beginning of the file if we don't have a gzip header.
    
    If the first byte of the file is 31, and we advance to the next byte but
    find it's not 139, back up to the first byte before falling through and
    treating the file as uncompressed.
    
    Add/expand some comments while we're at it.
