Make the empty body of for loops more obvious
    
    parseline() was skipping over non-option commandline args with 3 for
    loops that had empty bodies signified by semicolons at the end of the
    for() line (twice) or with a body comprised completely of a nested
    for() that had an empty body. Coverity didn't like this. Put braces
    around all three loop bodies to make the intent more clear.
