For example, one module could want to checkout 'master', while another might want
to checkout 'work'. The [-a|--customized-argument] argument provides platform
just for that. Consider the following command and its followup for further info:

If we want a useful and flexible "recurse", perhaps the only thing we need
to do is a command that lists a submodule directory path, one path at a
time, in optionally different traversal order and depth cutoff, so that
the user can feed it to xargs and do whatever they want to run in there.

I am not sure whether I understand it correctly or not, we could
simply provide the shell window by invoking 'sh', right? If we do that
then is there need to use xargs? I am not particularly experienced
with xargs, I was thinking of something as follows:

#!/bin/sh
echo "Submodule a"
(
PS1="module/submodule$" sh
)
echo "" #In case of ctrl+D to ensure that there is a blank line
echo "Submodule a ends"

I do agree that it would be powerful enough to serve all the necessary
purpose for traversing git submodules. If my assumption is right in
what we want then I will resubmit the patch with required changes.
