This is v3 of the diff-indent-heuristic patch series. Thanks to René,
Junio, and Ramsay for their comments about v2 [1,2].
The heuristic itself hasn't changed since v2. Most of the changes are
in the tests and in how `git blame` is wired up to support the new
options. Changes since v1:
* In "diff: improve positioning of add/delete blocks in diffs":
* Make `score_cmp()` static.
* Add test t4059 as part of this commit, not as part of its
successor.
* t4059: Create commits to use for the tests (rather than diffing
loose files with `--no-cache`), so that the same prep can be used
to test `git blame`. Split the tests into multiple smaller tests.
* Add a test that `--no-indent-heuristic` overrides the config.
* Add a new commit "parse-options: add parse_opt_unknown_cb()":
* Allow "-h" help text to be generated for options even if they are
being handled by code external to `parse_options()`.
If there's already a way to do this, I didn't find it.
* In "blame: honor the diff heuristic options and config":
* In v2, I suggested making `blame` honor all diff-related options.
Junio explained why this was a bad idea. So this version only
makes `blame` honor `--indent-heuristic` and
`--compaction-heuristic`.
* Add some smoke tests.
