[PATCH 0/3] merge -Xindex-only

[Thomas Rast <trast@inf.ethz.ch>]

[Michael, sorry for the double mail -- I typoed the list address on
the first round.]

I recently looked into making merge-recursive more useful as a modular
piece in various tasks, e.g. Michael's git-imerge and the experiments
I made in showing evil merges.

This miniseries is the extremely low-hanging fruit.  If it makes a
good first step for git-imerge, perhaps it can go in like this.  It's
not a big speedup (about 2.2s vs 2.4s in a sample conflicting merge in
git.git), but it does feel much cleaner to avoid touching the worktree
unless actually necessary.

Otherwise it's probably not worth it just yet; for what I want to do
with it, we need some more reshuffling of things.



Thomas Rast (3):
  merge-recursive: remove dead conditional in update_stages()
  merge-recursive: untangle double meaning of o->call_depth
  merge-recursive: -Xindex-only to leave worktree unchanged
