    xargs: fix -R so that it accepts negative numbers again
    
    fbc445addf9 converted the parsing of arguments to strtonum but made
    the accepted range for -R too restrictive. As documented in the man
    page, it should accept negative numbers.
    
    Added a test for this, which was provided by Jose Luis Duran.
