[bug] Git submodule command interprets switch as argument and switch

The issue is as follows:

R0b0t1@host:~/devel/project$ git submodule add
https://github.com/user/project -f
Cloning into '/home/R0b0t1/devel/project/-f'...

My .gitignore's first line is *, and then I explicitly allow things.
Despite the presence of "project/" in the .gitignore the submodule
command says it is ignored. The "force" flag is interpreted as a flag
and also as the destination directory.

It is possible the argument parsing code for other commands exhibits this error.
