Creates a path from the trailing elements of p that are relative
to base.
It may be more user-friendly to add that base must be a prefix of p.
It might be even more user-friendly to allow this use case:
BOOST_TEST(fs::relative("/abc", "/abc/def") == path("../def"));
The first element in the range p, that's not in base, is the empty set, so
p cannot be made relative to base in your example. If you reverse the
arguments, then the result would be "def".
