Thanks, I'll clean it up based on your comments. I based the tests
from t5606-clone-options.sh; I'm not sure why now but I thought I
needed that clone -o thing from there, but it appears useless.

--progress was missing from add command, was only in update.
Add --progress where it makes sense (both clone helper commands).
Add missing documentation entry.
Add test.

Maybe:
  The '--progress' was introduced in 72c5f88311d (clone: pass --progress
  decision to recursive submodules, 2016-09-22) to fix the progress reporting
  of the clone command. Also add the progress option to the 'submodule add'
  command. The update command already support the progress flag, but it
  is not documented.

The code looks good, though unlike the other commands progress is a
boolean decision.

If we want to support --no-progress as well, we can do so by adding
    --no-progress)
        progress="--no-progress"
        ;;
and then the submodule helper ought to cope with it.

Coding style:

        parens open on its own line, and its contents
        are indented by a tab.

Instead of coding this yourself, you could write the
test as:

    test_create_repo parent &&
    test_create_commit -C parent one

What are we testing here? I do not quite see the connection to
testing --progress here.

We're grepping for percent to see that there is no progress. At first I thought
the percent sign might be a special character, had to research it to know it's
meant literally. TiL!

Makes sense.

We could omit the extra shell by using

    git -C addtest submodule add "file://$... \
            >../out 2>../err &&

Why do we need 'out' ?

Thanks for writing these tests!
