How does it prevent you from saying

	git submodule "glib" ignore dirty

when you really meant "zlib"? How is the command supposed to know that you did *not* mean "glib", which may currently not exist in the index nor in the working tree yet but you are about to create, and doing the "ignore dirty" configuration as an earlier step of multiple steps to add a submodule?

I personally doubt that the main issue you should be concerned about is feasibility. A larger issue is how it is supposed to help, iow, is such a "feature" useful in the first place?

Whenever you hear yourself say "I have to do X manually, and I can make mistakes. Can a command do it instead?", you have to ask yourself: what pieces of information do you give to that command, and how do you ensure you do not make typos on that command line?

Besides, the above syntax would not work. What would a user do when a submodule called "add" exists, for example?
