Yikes. Can't "git pack-objects" get the input directly without
overlong printf, something along the lines of...
P1=$(git -C .git/objects/pack pack-objects pack <<-EOF
$A
$B
$C
...
$R
EOF
)

Move this to the next "expect success" block?

How portable is "sed -E" (it is not even in POSIX.1)? Wouldn't it
be easier to work with to have two "-e" fed to a single sed
invocation instead?
