bug: sparse config interpretation incorrectness in 2.8.0-rc2

Using git 2.8.0-rc2, given a repo with the following files:

- one/hideme
- one/donthide
- two/foo

A sparse config of:

cat > .git/info/sparse-checkout <<EOF /* !one/hideme EOF

Results in a repository that only has `one/donthide` in it. I would expect `two/foo`to be present as well. This worked in 2.6, and bisecting it points to d589a67eceacd1cc171bbe94906ca7c9a0edd8c5 "dir.c: don't exclude whole dir prematurely" (author cc'd).

The script I used to repro and for bisecting is pasted below:

#!/bin/bash

set -x rm -rf sparse-test GIT=git

$GIT init sparse-test cd sparse-test $GIT config --add core.sparsecheckout true

mkdir one two touch one/hideme touch one/donthide touch two/foo

$GIT add . $GIT commit -m "initial commit" $GIT read-tree --reset -u HEAD

mkdir .git/info cat > .git/info/sparse-checkout <<EOF /* !one/hideme EOF $GIT read-tree --reset -u HEAD

ls -R one two set +x echo echo expected: see one/donthide and two/foo echo actual: see only one/donthide

[ -d two ] && exit 0 exit 1
