t/t7407: demonstrate that the command called by 'submodule foreach' loses stdin
The user-supplied command spawned by 'submodule foreach' loses its
connection to the original standard input. Instead, it is connected to the
output of a pipe within the git-submodule script. This can cause a problem
if the command requires reading from stdin or if it changes its behavior
based on whether stdin is a tty or not (e.g. git shortlog). Demonstrate
this flaw.
