Details:

GNUstep doesn't have a method equivalent to CFURLCopyPath, which returns the
path portion of a URL *without* decoding %-escapes. This is important if you
need to be able to work with paths that contain quoted slashes, i.e. "%2F"
escapes -- the regular NSURL.path method decodes all the escapes so you can no
longer tell %2F apart from /.

My app needs this functionality. (In the REST API I'm working with, path
components may contain slashes if they are escaped as %2F.) In the original
Mac/iOS code I use CFURLCopyPath, but I couldn't find a good way to do this in
GNUstep. I don't want to bring in the entire CoreBase framework just for that
one function.

Looking at NSURL.m, all I need to to is prevent one call to unescape(). I
added a boolean parameter indicating whether to leave the escapes. So the
existing -path method passes NO, and I created a new -pathWithEscapes method
that passes YES.

Attached is a patch that implements this.
