    crypt: Fix hash line format compatibility
    
    According to the coreutils implementation man-page (of sha512sum),
    
> The sums are computed as described in FIPS-180-2. When checking, the
> input should be a former output of this program. The default mode is
> to print a line with: checksum, a space, a character indicating input
> mode ('*' for binary, ' ' for text or where binary is insignificant),
> and name for each FILE.
