clojure.string/split and clojure.string/split-lines inherit the bizarre default behavior of java.lang.String#split(String,int) in stripping trailing consecutive delimiters:
In the case of split-lines, processing a file line by line and rejoining results in truncation of trailing newlines in the file. In both cases, the behavior is surprising and cannot be inferred from the docstrings. A workaround for split is to pass a limit of -1.
Proposed: As current users may be relying on the current behavior, the attached merely updates the docstring to warn of this behavior and suggest use of -1 as a limit to workaround.
