[Pharo-project] String>>beginsWith: with empty strings issue

Hi, I noticed that 'pharo' beginsWith: '' returns false. Is that Ok? I expect that this returns true, because the empty string is a prefix (and suffix) of any other string. Similar behavior exhibits endsWith:. This seems a bug to me. What do you think? In case we acknowledge it's a bug I can post an entry in the issue tracker and tonight upload a SLICE with the fix.
