git-svn: Fails to drop leading path from empty dir name

["Björn Steinbrink" <B.Steinbrink@gmx.de>]

Hi Eric,

the stuff to create empty directories fails to strip leading path
components, e.g. when using
"git svn clone -s svn://whatever/project/trunk".

Instead of creating the empty directory "foo" in the repo root, it
creates "project/trunk/foo".

Ad hoc patch for the test case below.

Björn
