Teach update-index to read from ls-tree.
git-update-index --index-info can almost be usable to read from ls-tree output to update the index (and not the working tree file) to HEAD commit, but not quite. It was designed to read from git-apply --index-info output, and does not want " blob " in ls-tree output. Accept that as well. This lets us update "git-checkout <ent> <path>" that used to filter the extra " blob " string out. Noted by Luben. Signed-off-by: Junio C Hamano <junkio@cox.net>
