Up until now hudson determines the directories of the modules it by selecting
the last path component of the subversion URL:
http://<svn>/<path>/module1 into directory module1
http://<svn>/<path>/module2 into directory module2

But if the paths end up with the same directory this will cause problems as
hudson will checkout multiple projects into the same directory
e.g:
http://<svn>/<path>/module1/trunk into directory trunk
http://<svn>/<path>/module2/trnuk into directory trunk <- conflict.

It should be possible to define for each repository location a custom target
directory ot avoid conflicts.
