Subject: unpack-trees(): add CE_WT_REMOVE to remove on worktree alone
X-Git-Tag: v1.7.0-rc0~103^2~13
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=e663db2f446b84bfe39b4dcb3d26b33826d52c1a;p=git.git

unpack-trees(): add CE_WT_REMOVE to remove on worktree alone

CE_REMOVE now removes both worktree and index versions. Sparse
checkout must be able to remove worktree version while keep the
index intact when checkout area is narrowed.
