I missed that it echoed chars...

You defined the function as "void", meaning that it doesn't return a value. An
empty "return" just exits the function - and can be placed anywhere *within* the
function, even inside several levels of nested loops. But here it's both at the
very end of the function _and_ in a function that doesn't return anything - so
it's not necessary at all.
(Of course, it might have been optimized away depending on how smart the
compiler is)
