+Empty leading fields are produced when there are positive-width matches at

+produces the output 'h:i :t:h:e:r:e!'. Empty trailing fields, on the other
+hand, are produced when there is a match at the end of the string (and
+when LIMIT is given and is not 0), regardless of the length of the match.
+For example:
+
+ print join(':', split(//, 'hi there!', -1));
+ print join(':', split(/\W/, 'hi there!', -1));
+
+produce the output 'h:i: :t:h:e:r:e:!:' and 'hi:there:', respectively,
+both with an empty trailing field.
The LIMIT parameter can be used to split a line partially
