    clone: extract helper for checking mutually exclusive args · d587937600be
    Martin von Zweigbergk authored
    We have some duplicated code for aborting if the user provided
    mutually exclusive arguments. Extensions surely have more such
    code. We also have duplicated translations and inconsistent output in
    this area.
    
    This patch introduces a simpler helper for checking if more than one
    option among a given set was given on the command line. I've made the
    clone code call the function to show that it works.
    
    The function has no good way of checking arguments with hyphens in
    them. I'll add that later if necessary. The function still won't be
    applicable in all cases, but I think it's still better than nothing.
