As a general principle, we should not use "git diff" to validate the
results of what git command that is being tested has done. We would not
know if we are testing the command in question, or locating a bug in the
cute hack of "git diff --no-index".
Rather use test_cmp for that purpose.

This uses "git-apply --whitespace=strip" to fix whitespace errors that have
crept in to our source files over time. There are a few files that need
to have trailing whitespaces (most notably, test vectors). The results
still passes the test, and build result in Documentation/ area is unchanged.

We have fairly extensive coverage of read-tree 3-way machinery,
and many Porcelain-ish tests use git-merge front-end tests, but
we did not have good basic test for merge-recursive, which made
it very hard to hack on it.
I used this during the recent work to teach D/F conflicts to
merge-recursive.
