[PATCH v2 0/6] Clean up tests for test_cmp arg ordering and pipe placement

This applies the suggestions from jrn@'s response to v1 here: https://public-inbox.org/git/20180917163137.GB89942@aiede.svl.corp.google.com/

The major changes are:
 - Added two bullet points to Documentation/CodingGuidelines about 1) how to
   format pipe sequences and 2) using temporary files rather than pipes to
   avoid masking potiential error exit codes.
 - A new commit which introduces a linter check to enforce (1) above, which I
   am requesting feedback for. I'd be happy to drop it.
 - A new commit to fix violations of (2) above in t9101-git-svn-props.sh since
   it was not so trivial.
 - A better message to describe the pipe placement commit.

Thank you,

Matthew DeVore (6):
  CodingGuidelines: add shell piping guidelines
  tests: standardize pipe placement
  t/*: fix ordering of expected/observed arguments
  tests: Add linter check for pipe placement style
  tests: split up pipes
  t9109-git-svn-props.sh: split up several pipes
