Tries to make a relative filename from absolute path and filename.
Attempts to make a relative filename from an absolute path and an absolute
filename, storing at most `size' bytes into the `dest' buffer. This
function won't work if the paths are not canonical under the current
platform (see canonicalize_filename()). Also, `dest' cannot be used as
input value for `path' or `filename'. Example:
char base = "/long/absolute/path/program.exe";
char user_input = "/nice/and/short.txt";
make_relative_filename(buf, base, user_input, sizeof(buf));
/* Under Unix buf would contain:
Returns a copy of the `dest' parameter if it succeeds or NULL if it fails
(eg. under DOS, one path starts with "C:\" and another with "A:\").
