Review request for kdelibs.


Summary
-------

Currently, if you have:

 KUrl test("foo.txt");

Then test.path() returns "foo.txt" and so does test.pathOrUrl(). But after you call test.setFileName("bar.txt"), test.path() and
test.pathOrUrl() both return "/bar.txt".

This patch makes setFileName not add this extra slash when there is no directory in the current path, and also cleans up some dead code.

Testing
-------

I have tested it with local files as in the example given in the description. Using a path like "http://www.kde.org/test/foo.txt" and later calling setFileName maintains its correct behaviour -- path() returns "/test/bar.txt" and pathOrUrl() returns "http://www.kde.org/test/bar.txt".


Thanks,
