OK, parenthese after function name.

Find that no space before <OID>, because git-pack-objects not allow that,
and mached parentheses should in the same line.
So Will write like this:
create_pack_1() {
P1=$(git -C .git/objects/pack pack-objects pack <<-EOF) &&
$T
$A
$B
$R
EOF
eval P$P1=P1:$P1
}

$P4 and $P5 are defined after calling `create_pack_4` and `create_pack_5`,
so create pack functions should be called before write `expected` file,
if puts $P4 and/or $P5 in the expected file.
For this case, $P4 and $P5 not in expected file, we can move
create_pack_4 and 5 to the following test_expect_success block,
but the new algorithm may change the expected file.

will fix using two '-e' commands.
