Subject: [PATCH] Change string::split once more - Delimiters now end up in
 their own token when keepSeparators is true. - When ignoreEmptyTokens is
 false we now add a token at the end when the last character is a delimiter.
 While this means some changes, the ignoreEmptyTokens=false didn't work
 correct in 1.8 anyway, so another change shouldn't break much. Thanks
 @manni63 for bringing this up in forum:
