rm: better document side effects when removing a submodulejl/submodule-mv-checkout-caveat
The "Submodules" section of the "git rm" documentation mentions what will
happen when a submodule with a gitfile gets removed with newer git. But it
doesn't talk about what happens when the user changes between commits
before and after the removal, which does not remove the submodule from the
work tree like using the rm command did the first time.
Explain what happens and what the user has to do manually to fix that in
the new BUGS section. Also document this behavior in a new test.
