Patchset:

PS1: in general I think the opposite conservative approach would be best: Never use wildcards to delete anything (unless it's in a tmp-directory with random-generated name generated by mktemp or the like), but always use only those explicit names we know we have created ourselves. Otherwise you always have the risk of deleting something that was not created by the tests.
