[PATCHv2 0/2] Fix rerere segfault with specially crafted merge




This series documents and fixes a rerere segfault (dating back to
git-2.7.0) when a merge strategy makes the last entry in the index be
at stage 1.

Changes since last version:
  - In my last submission I only had the code fix and no testcase; I
    even commented in the commit message that the bug "cannot be
    triggered in the current codebase" and mentioned that I was fixing
    it just because an exotic external merge strategy could trigger
    the bug.  I realized later that it is triggerable without any
    exotic external merge strategies; built-in ones can do it.
