From de84f99c12d1819479116685393afb1ebe99810b Mon Sep 17 00:00:00 2001 From: Shawn Pearce Date: Sun, 5 Mar 2006 03:24:15 -0500 Subject: Add --temp and --stage=all options to checkout-index. Sometimes it is convient for a Porcelain to be able to checkout all unmerged files in all stages so that an external merge tool can be executed by the Porcelain or the end-user. Using git-unpack-file on each stage individually incurs a rather high penalty due to the need to fork for each file version obtained. git-checkout-index -a --stage=all will now do the same thing, but faster.
