You don't need the line above when you are the sender ;-)

That's a bit terse. What about:

"Add the verbose flag to add and update which displays the
 progress of the actual submodule checkout when given. This
 is useful for checkouts that take a long time, as the user
 can then see the progress."

The above looks whitespace-damaged, you should use TABs here to
indent (just like the other options do).

Wouldn't it be better to use the ${subquiet:+"$subquiet"} notation
here like the other optional arguments do? After all the subquiet
isn't always set.

Same as above.

This string is translated, so you need to use test_i18ngrep.
Please see t7201-co.sh for an example of how to pipe the
