Details:

According to the GNUstep documentation:
 If the string cannot be parsed the method returns nil.
According to the Cocoa documentation:
 The NSURL class will fail to create a new NSURL object if the path being
passed is not well-formed—the path must comply with RFC 2396. Examples of
cases that will not succeed are strings containing space characters and
high-bit characters. Should creating an NSURL object fail, the creation
methods will return nil, which you must be prepared to handle.

However, the test:
  NSURL *url = [NSURL URLWithString:@"this isn't a URL"];
  NSLog (@"Got URL: %@", url);
2006-12-01 12:02:26.066 basic[6402] URL: this isn't a URL
shows that non-conforming URLs don't cause a nil return.

I've codified this as a test on NSURL, with the patch to the testsuite
attached.
