Junio C Hamano fdf3a27ca9 Merge branch 'jx/t5411-unique-filenames'
Avoid individual tests in t5411 from getting affected by each other
by forcing them to use separate output files during the test.

* jx/t5411-unique-filenames:
  t5411: refactor check of refs using test_cmp_refs
  t5411: use different out file to prevent overwriting

# Format the output of git-push, git-show-ref and other commands to make a

# without having to worry about future changes of the commit ID and spaces
# of the output. Single quotes are replaced with double quotes, because
# it is boring to prepare unquoted single quotes in expect text. We also
# remove some locale error messages. The emitted human-readable errors are
# redundant to the more machine-readable output the tests already assert.
