    md5(1): Warn on read errors
    
    md5(1) previously did not report read errors.  As a result, attempting
    to hash a directory produced no output and only returned exit code 66.
    
    Make md5(1) print a warning when a file cannot be read.
    
    Before:
        $ md5 /
        (no output; only exit code 66)
    
    After:
        $ md5 /
        md5: can't read /: Is a directory
