git submodule add https://my-git-repo blort git commit -m 'add a submodule' git reset HEAD^ blort
The reset deletes the gitlink, but does not delete the entry in .gitmodules. On one hand, this is exactly what the user asked for -- they wanted the path 'blort' to be changed in the index, and that's what they got. On the other hand, the behavior differs from git rm, and seems confusing: most folks don't want an entry in .gitmodules which doesn't correspond to a gitlink. If reset isn't the right thing for me to do when I want to say "oops" about adding a submodule, then what is? I could do: git reset HEAD^ blort .gitmodules but what if I added two submodules and only wanted to undo the addition of one?
