[PATCH v6 0/7] short status: improve reporting for submodule changes

[Stefan Beller <sbeller@google.com>]

v6:
* kill the child once we know all information that we ask for, as an optimization
* reordered the patches for that
* strbuf_getwholeline instead of its _fd version.

v5:
* fixed rebase error in the first 2 patches
* the last 3 patches introduce behavior change outside the scope of is_modified_submodule
  whereas the first 4 ought to just be local changes.
  
Thanks,
Stefan

v4:
* broken down in a lot of tiny patches.

This part is in the latest patch now.

Thanks,
Stefan


v3:
This comes as a series; first I'd like to refactor is_submodule_modified
to take advantage of the new porcelain=2 plumbing switch to check for changes
in the submodule.

On top of the refactoring comes the actual change, which moved the
rewriting of the submodule change indicator letter to the collection part.

Thanks,
Stefan
