[PATCH 0/2] Simple fixes to t7406

[Elijah Newren <newren@gmail.com>]

Changes since v1:
  - Simplify multiple tests using diff --name-only instead of diff --raw;
    these tests are only interested in which file was modified anyway.
    (Suggested by Junio)
  - Avoid putting git commands upstream of a pipe, since we don't run under
    set -o pipefail (Suggested by Eric)
  - Avoid using test_must_fail for system binaries (Pointed out by
    both Eric and Junio)

  t7406: simplify by using diff --name-only instead of diff --raw
  t7406: avoid having git commands upstream of a pipe
  t7406: make a test_must_fail call fail for the right reason
