Comment (by jzlomek):

 It is better but still not correct. Consider this test:

 test("http://server/foo/bar",
 "a/b/../c/d/../e../.../..f/g../h../other/url/a.mp3/...");
 It should give
 "http://server/foo/bar/a/c/e../.../..f/g../h../other/url/a.mp3/...".

 I think the best would be to use strtok(p, "/") to split the path into the
 components and for each ".." component remove the previous one (if there
 are some still).
