   ifelse is special, fix argv parsing to avoid segfault
   problem noticed by Matthew Green (netbsd), slightly different fix
   so that argc counting makes more sense.

   we might want to warn on wrong number of parameters later, but this is
   somewhat inconsistent depending on the builtin right now.
