[BUG?] "git submodule foreach" when command is ssh

Hi All,

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 the first module (note that the command does produce the expected listing and there is no error about the command failing).

git submodule foreach 'echo foo' - works as expected

Any thoughts as to whats going on?
