git/git-merge-resolve.sh
Junio C Hamano 1b1fdf8c2f read-tree --aggressive
A new flag --aggressive resolves what we traditionally resolved
with external git-merge-one-file inside index while read-tree
3-way merge works.

git-merge-octopus and git-merge-resolve use this flag before
running git-merge-index with git-merge-one-file.
