My argument is only that default behavior with *no* local configuration
should not touch anything outside the source or build tree.  This would
be like saying that

 git clone git://some/repo.git clone1
 git clone git://some/repo.git clone2

should magically share a Git object database somewhere outside either
tree, like ~/.gitobjects/ for example.  Then following the above with

 rm -rf clone1 clone2

would not actually erase the local copy of objects from repo.git or
fully un-do the original clone operations.
