[PATCH v3 0/8] --remerge-diff

[Thomas Rast <tr@thomasrast.ch>]

This is a resend of the remerge-diff patch series, previously posted
here:

  http://thread.gmane.org/gmane.comp.version-control.git/242514

Differences to the previous version:

- Rebased onto the new {name,dir}_hash maps (7/8 looks very different
  now).  This also allows freeing index entries that we no longer need
  (in 8/8); previously, the insert-only name-hash kept them alive.

- Adaptations to match Duy's changes to cache_tree handling (in 8/8).
  Please review the cache_tree handling extra carefully, as I'm not
  100% convinced the dance there is all that is needed.



Thomas Rast (8):
  merge-recursive: remove dead conditional in update_stages()
  merge-recursive: internal flag to avoid touching the worktree
  merge-recursive: -Xindex-only to leave worktree unchanged
  combine-diff: do not pass revs->dense_combined_merges redundantly
  Fold all merge diff variants into an enum
  merge-recursive: allow storing conflict hunks in index
  name-hash: allow dir hashing even when !ignore_case
  log --remerge-diff: show what the conflict resolution changed
