Arglist being passed as arguments while empty

[KittyGiraudel]

Test

.foo {
  content: call('unquote', 'foo', ()...);
}

Expected

.foo {
  content: foo;
}

Actual

function quote only takes 1 arguments; given 2 on line 2 at column 12

Observations

Does not matter the function. When passing an empty list as extra arguments, LibSass pass the empty list as another argument instead of discarding it.
