Hi Lukasz,

Sorry, but I do not use it. I will send You a normal email.
I have added two options to git submodule update:
--save-progress
--resume-update
First one You can use, to save the ./.git/SubmoduleUpdateLog.log the
progress of updating:
git submodule update --recursive --save-progress
The second one is used for skipping updated submodules:
git submodule update --recursive --resume-update
The downside of it is, that u can use only one --resume-update. If there
will be another error, then using it again will start form the last
submodule that --save-progres saved.
I have send two files:
"git-submodule" - it has my changes
"git-submodule - Original" - it not modyfied
so that You can see what lines I have added.
Let me know if this change will be in next version of git.
Best regards,
Lukasz Palczewski
