[PATCH v2 05/11] Add "skip_unmerged" option to unpack_trees.
From: Daniel Barkalow <hidden>

This option allows the caller to reset everything that isn't unmerged, leaving the unmerged things to be resolved. If, after a merge of "working" and "HEAD", this is used with "HEAD" (reset, !update), the result will be that all of the changes from "local" are in the working tree but not added to the index (either with the index clean but unchanged, or with the index unmerged, depending on whether there are conflicts). This will be used in checkout -m. Signed-off-by: Daniel Barkalow <redacted> --- unpack-trees.c | 20 +++++++++++++++++--- unpack-trees.h | 1 + 2 files changed, 18 insertions(+), 3 deletions(-)
