Details:

r31501 in NSURL.m somehow managed to do exactly the wrong thing. It added
question mark and semicolon to the set of characters that would be
percent-escaped, but this is incorrect, and incompatible with Mac OS X.

This tiny test demonstrates the problem:

void test()
{
    NSURL *u = [[[NSURL alloc] initWithScheme:@"http" host:@"1.2.3.4"
path:@"/a?b;foo"] autorelease];
    NSLog(@"url = %@", [u absoluteURL]);
}


On Mac OS X 10.6.8, it prints:

2012-02-02 11:42:51.673 urltest[410:903] url = http://1.2.3.4/a?b;foo

With gnustep-base 1.22.0 it prints:

2012-02-02 16:43:08.276 urltest[1743] url = http://1.2.3.4/a%3Fb%3Bfoo
