Hi,

I tried debugging into it:
In git/t/t1304-default-acl.sh there is:
check_perms_and_acl () {
   test -r "$1" &&
   getfacl "$1" > actual &&
   grep -q "user:root:rwx" actual &&
   grep -q "user:${LOGNAME}:rwx" actual &&
   egrep "mask::?r--" actual > /dev/null 2>&1 &&
   grep -q "group::---" actual || false
}

but when I do all the commands as in the test2:
test_expect_success SETFACL 'Objects creation does not break ACLs with
restrictive umask' '
   # SHA1 for empty blob
   check_perms_and_acl .git/objects/e6/9de29bb2d1d6434b8b29ae775ad8c2e48c5391
'
Now I run the second line in check_perms_and_acl ()  with
.git/objects/e6/9de29bb2d1d6434b8b29ae775ad8c2e48c5391
there is

getfacl .git/objects/e6/9de29bb2d1d6434b8b29ae775ad8c2e48c5391 # file: .git/objects/e6/9de29bb2d1d6434b8b29ae775ad8c2e48c5391 # owner: sb # group: sb user::r-- user:root:rwx #effective:--- user:sb:rwx #effective:--- group::--- mask::--- other::---

This command seem to fail 'egrep "mask::?r--" actual' as there is mask::--- but expected is mask::r--

That's my understanding of the test case so far.
