#139: Existing symbolic links not deleted

 Priority:  major          |   Milestone:       
Component:  GetComponents  |     Version:

 I had a case where a git repository did not exist any more, but the
 symbolic links pointing into the git repository were still there.
 GetComponents then checked out the repository, and then got confused -- it
 created links inside the repository (which it is not supposed to modify!)
 pointing nowhere.

 I think ln should be called as "ln -nsf", or the link (if it exists)
 should be deleted before the new link is created.
