I don't think it would. The / operator understands absolute paths and doesn't
add the "first component" if the second component is absolute.

Hm, I'm not sure this works entirely right on windows. A path like /blub isn't
absolute on windows, but it's not really relative either. It's a "drive local"
path. I.e. relative to the current drive (c:/), but not the subdirectory
therein.
