Summary:                    ARGN stripped of empty elements
Description: 

When creating a function with optional arguments, ARGN is strip of empty
arguments.
This means one cannot use ARGN for optional arguments that are ordered.

function(foo arg1 arg2)
  message("ARGV=${ARGV}")
  # should give "arg1;arg2;;arg4"
  message("ARGN=${ARGN}")
  # should give ";arg4" instead of "arg4"
endfunction(foo)

foo("arg1" "arg2" "" "arg4")
