[PATCH 0/2] fix a segfault in get_main_ref_store()

[Jeff King <peff@xxxxxxxx>]

I stumbled across a BUG() today. But interestingly, in the current tip
of master it actually segfaults instead! This fixes the segfault (back
into a BUG(), and then fixes the caller to avoid the BUG() in the first
place).

  [1/2]: get_main_ref_store: BUG() when outside a repository
  [2/2]: config: die when --blob is used outside a repository
