[PATCH v4 0/4] add notes strategy configuration options

From: Jacob Keller <jacob.keller@gmail.com>

This series of patches implements notes.merge and notes.<ref>.merge options for configuring notes merge strategy such that user may avoid typing "-s". It is (probably) most useful if the user wishes to always enforce cat_sort_uniq strategy.

This series now uses git_config_get_string_const() instead of trying to change the git_default_config setup. In addition, the 4th patch is much smaller and avoids a lot of heavy cruft due to this change.

I tried to re-work everything I noticed from the email list, but please shout if I did not manage to recall your suggestion.

The new version should be much simpler to understand.

Changes since v3:
* don't use hash table, instead just call "git_config_get_string_const"
* notes.<ref>.merge must always be fully qualified, (since notes doesn't
  enforce the refs to be always in refs/notes, so we shouldn't either)
* fixed documentation to reduce confusion over which strategies are
  accepted for options
* ensure tests cover "notes.<ref>.merge" overrides "notes.merge"

I also tried to make sure the reviewers were all Cc'ed on every patch not just the first one this time.

Jacob Keller (4):
  notes: document cat_sort_uniq rewriteMode
  notes: add tests for --commit/--abort/--strategy exclusivity
  notes: add notes.merge option to select default strategy
  notes: teach git-notes about notes.<ref>.merge option
