Then you do something like:

rm -rf module_{a,b,c}/.git # Do this in a test repository, obviously...
git add module_a module_b module_c
git commit # Needed because '-s ours' uses current HEAD, not index

So far so good.

git merge --no-commit -s ours module_a/master module_b/master module_c/master

Hm.  I did mention this was completely untested, yes?  The problem comes
from the fact that '-s ours' wants to use HEAD, not the index.  But you
can't amend a normal commit into a merge, apparently.  And I don't think
you want a commit that adds the files and a commit that "does the merge"
as two separate steps.

Well, I don't know how to make the porcelain do this then. But the
plumbing can definitely do it.  Hopefully someone more used to doing
strange things like this can give a simpler recipe, but this should
work.

# First reset to the commit you made with all the modules added.
vim commit-message # Create a merge message
commit=$(git commit-tree HEAD: -p HEAD^ -p module_a/master -p
		module_b/master -p module_c/master < commit-message)
git update-ref HEAD $commit  # Update your current ref
