The bad news is... it just got bigger ;-)

So here's a 4-patch series.  I put the first split in a different
place than you suggested, however.  I couldn't see a good way to
separate empty boundaries from regex splitting in such a way that the
first half can be exercised (is not just dead code).  1/4 basically
just rearranges code a bit and should be a real no-op patch.

Thanks, added a case to test for this.

There is one other minor semantic change in 2/4: the error reporting
in case your regex matched "foo\nbar" now says "before 'bar'" instead
of "near '\nbar'".  Other than that, there are only a bunch of added
comments when comparing the result of all four patches with v2.
