 As mentioned in the '[boost] [filesystem] "leaf"' thread, complete is the
 only path composition function without a corresponding decomposition
 function.

 The idea: uncomplete(/foo/new, /foo/bar) => ../new

 The use case for this is any time you get a full path (from an open
 dialog, perhaps) and want to store a relative path so that the group of
 files can be moved to a different directory without breaking the paths.
 An IDE would be a simple example, so that the project file could be safely
 checked out of subversion.

 I'd like to call it relative, but that conceptually conflicts with the
 relative_path member decomposition function.  Perhaps the member function
 could be changed to local_path(), or something.

 A discussion will need to be held to determine expected behaviour in the
 presence of symlinks, since root/foo/bar/.. is not always root/foo.
