I don't see the point of lines below that comment "# Scripts don't get
the current directory in their path by default.". I'm adding a patch
that removes those lines and makes use of pathdirs function instead of
using sys.path in serve function, so you get unique paths and some other
things that pathdirs does. If pathdirs shouldn't be used then it should
be removed as well, because it was not been used anywhere else. It seems
sometime this was changed by mistake.
