[PATCH v2 1/5] git-submodule.sh: Add Long Usage instead of simple usage

[imyousuf@gmail.com]

From: Imran M Yousuf <imyousuf@smartitengineering.com>

With the already available commands the synopsis is quite hard to
read; thus converted it to Long usage instead. In process also
updated the file comment.
