Fixed a bug in `absolute' and `absolute_in' where if you have the following path `c:abc.txt' and you try to get the absolute path where the current working directory is c:\foo\bar, the resulting path should be `c:\foo\bar\abc.txt' and not just `c:\abc.txt'.
This fix new case from eweasel test#path002 (rev#91081).
