The presence of an extra comma would leave me second-guessing the
behavior on multiple returns too. In any case, it should do the same
as the table constructor. Went to check what the table constructor

Lua 5.1.2  Copyright (C) 1994-2007, PUC-Rio
function f() return 1, 2 end
t = { f() }
print(t[1], t[2])
1    2
u = { f(), }
print(u[1], u[2])
1    2
v = { f(), 3 }
print(v[1], v[2])
1    3
So, yes, if function calls were to accept a trailing comma, I think
they should just drop the comma and not impose special behavior on
multiple returns, for consistency with the table constructor.

But code golfing... :(
