Yes I'd expect that too. But the **collapse** operation in paste() has
never been about collapsing **multiple** character vectors together.
What it does is collapse the **single** character vector that comes out
of the 'sep' operation.
paste(x, y, z, sep="", collapse=",")
is analogous to
sum(x + y + z)
The element-wise addition is analog to the 'sep' operation.
The sum() operation is analog to the 'collapse' operation.
