Fix build by turning a comment into a doc comment. Clarify logic.

Now I see what jessewilson was trying to say earlier; rewrite the post-loop
code to say what I guess it was aiming at, which is avoiding an add followed
by a remove in the not completely uncommon case where limit == 0 and the
regular expression is a terminator rather than a true separator ('\n', say).
(Normally the regular expression is a true separator so there will be no
trailing empty string even though limit is 0: "a,b,c".split(","), for example.)

Also, String.isEmpty is our fasest way of recognizing the empty string;
certainly better than equals("").
