[PATCH v3 0/5] Fix use of uninitialized hash algorithms

[Junio C Hamano <gitster@pobox.com>]

In this round, the escape hatch is no longer the escape hatch, but
also serves as an end-user knob to specify what hash algorithm to
use when there is no repository to tell us which one to use.

We can see that Patrick's two fixes to patch-id and hash-object, as
well as my fix to apply, correct the breakage as the series
progresses.

Junio C Hamano (3):
  setup: add an escape hatch for "no more default hash algorithm" change
  t1517: test commands that are designed to be run outside repository
  apply: fix uninitialized hash function

Patrick Steinhardt (2):
  builtin/patch-id: fix uninitialized hash function
  builtin/hash-object: fix uninitialized hash function
