Title: splitter ddoc and constraint improvements.

splitter requires a sliceable range, contradicting
the ddoc. Additionally, one of the overloads
requires a sliceable range, but omits this from
the if-constraint.

This commit mentions the sliceable constraint in
the ddoc and tightens the constraints of the
overload to require slicing.
