Well, we could run GetFullPathName() on it
(http://msdn2.microsoft.com/en-us/library/aa364963.aspx). I think that
should work - takes out the "relative vs absolute path" part at least.
It won't take care of somebody having a junction pointing at the data
directory and starting it against that one, but that's really someone
*trying* to break the system. You wouldn't do that by mistake...
Seems worthwhile to you? If so I can take a look at doing it when I get
some spare time.
