Re: stringByTrimmingCharactersInSet (work-around)

Hi All.

One work-around is to simply append a space to the string before
trimming. Like this:

    value = [value stringByAppendingString: @" "];
    value = [value stringByTrimmingCharactersInSet: [NSCharacterSet
whitespaceCharacterSet]];

Not pretty, but the good thing is this code will continue to work after
Apple fixes stringByTrimmingCharactersInSet:.
