Previously the exit status of git submodule was zero for various
subcommands even though the user specified an unknown path.
The reason behind that was that they all pipe the output of module_list
into the while loop which then does the action on the paths specified by
the commandline. Since piped commands are run in parallel the status
code of module_list was swallowed.
We work around this by introducing a new function module_list_valid
which is used to check the leftover commandline parameters passed to
module_list.
