The first command:
git submodule --quiet foreach echo 'a  b' '"c  d"'
gives the output: a  b "c  d"
Where there is a double space between a and b while c and d still retain
their quotes.

The second command:
git submodule --quiet foreach 'echo a  b "c  d" "$sha1"'

Gives the output:
a b c  d 0ac90c5a98030c998f3e1db3a0d7f19d4630b6b6
So, it does seem to do word splitting between a and b, while retaining the
double space between c and d.
