Hmph, if I have "A, B, C" and call a function that gives an array of
addresses, treating the input as comma-separated addresses, I would
expect ("A", "B", "C") to be returned from that function, instead of
having to later trim the whitespace around what is returned.

It suggests that split-at-commas _is_ a wrong abstraction, doesn't
it?  In other words, I think whitespace trimming is part of what the
split-a-single-string-into-array-of-addresses helper function should
be doing.
