And i thought about printing just one line for each dirty submodule that
contains uncommitted and/or new files. I did not intend to list every
file, for the same reason a "git diff --submodule" only shows the first
line of the commit messages, not the actual differences of all changed
files in the submodule. I am not against being able to show all files
too, but i really would want to have an option to get a short output for
git gui and gitk.
