|
Test pruning of repositories with minor corruptions. The goal |
|
here is that we should always be erring on the side of safety. So |
|
if we see, for example, a ref with a bogus name, it is OK either to |
|
bail out or to proceed using it as a reachable tip, but it is _not_ |
|
OK to proceed as if it did not exist. Otherwise we might silently |
|
delete objects that cannot be recovered. |
