[PATCH 0/8] The return of -Xours, -Xtheirs, -Xsubtree=dir

["Avery Pennarun" <apenwarr@gmail.com>]

As discussed earlier today, this brings back Junio's earlier patch series
that introduced (and then used) a -X option for configuring merge
strategies.  My favourite use of this is -Xsubtree=<dir>, which lets you
provide the actual subdir prefix when using the subtree merge strategy.

Avery Pennarun (8):
  git-merge-file --ours, --theirs
  builtin-merge.c: call exclude_cmds() correctly.
  git-merge-recursive-{ours,theirs}
  Teach git-merge to pass -X<option> to the backend strategy module
  Teach git-pull to pass -X<option> to git-merge
  Make "subtree" part more orthogonal to the rest of merge-recursive.
  Extend merge-subtree tests to test -Xsubtree=dir.
  Document that merge strategies can now take their own options
