If I run git submodule foreach each '$name', then my shell eats the
single quotes (which are only to prevent my shell from interpreting
$name). git submodule will see $name, so it will run echo $name, not
echo '$name'.

Then my shell eats up the double quotes _and_ replaces $name with
nothing, so I can't expect git submodule to replace it with the
submodule name then :-)

Does that help to clarify what I mean?
