Right, having ploughed through yet another of your complex sets of examples, I
can see no bug here; or rather nothing very surprising: [[test:Template:Sign]]
uses three variables, called '1', '2', and '3', and you are only supplying one
unnamed parameter, which is assigned the name '1'. The behaviour for missing
parameters, in the version running on [[test:]], is simply to output the text as
though it wasn't valid syntax (as I explained at bug 364#c2) - so "{{{2}}}" is
just output as "{{{2}}}". So your template is behaving as expected.
