If we use a different conflict style `git rerere forget` is not able to find the matching conflict SHA-1 because the diff generated is actually different from what `git merge` generated, due to the XDL_MERGE_* option differences among the codepaths. The fix is to call git_xmerge_config() so that git_xmerge_style is set properly and the diffs match.
