    I just noticed something odd with "git submodule foreach". I was
    running a script to create a backup of each submodule on a server I
    have ssh access to. I was surprised to find that git submodule foreach
    stopped silently after the first submodule.

    A little debugging and I find that

    git submodule foreach 'ssh localhost "ls /"' - stops silently after

Putting some input redirection will work around the problem. Presumably some pipe input is going into the ssh accidentally.

git submodule foreach 'ssh localhost "ls /" < /dev/null'

I'll also just take this moment to advertise gitslave (http://gitslave.sf.net) as an alternate to submodules which may help (or hinder) you--depending on your workflow. It doesn't suffer from this particular problem in any case.
