      loplugin:stringadd
    
      tweak the plugin to be more permissive, then validate by hand
      afterwards
    
    which replaced strFor.replaceAt(0,1,"") with strFor.copy(1). Both methods
    are illegal on empty string, but the former asserted, then silently corrected
    wrong count; while the latter returns "br0ken". So the change actually
    revealed a pre-existing bug.
