Quoting the documentation[1]:

  If any one of the individual segments is an absolute path,
  all segments before it are dropped. That means that
  join_paths('foo', '/bar') returns /bar.

Wow, that is some magic going on right there! Not sure whether I
like it, but it's not my decision to make anyway :)

The patch itself is correct, so
