Merge branch 'sb/submodule-short-status'
The output from "git status --short" has been extended to show various kinds of dirtyness in submodules differently; instead of to "M" for modified, 'm' and '?' can be shown to signal changes only to the working tree of the submodule but not the commit that is checked out. * sb/submodule-short-status: submodule.c: correctly handle nested submodules in is_submodule_modified short status: improve reporting for submodule changes submodule.c: stricter checking for submodules in is_submodule_modified submodule.c: port is_submodule_modified to use porcelain 2 submodule.c: convert is_submodule_modified to use strbuf_getwholeline submodule.c: factor out early loop termination in is_submodule_modified submodule.c: use argv_array in is_submodule_modified

Submodules have more state and instead report

M the submodule has a different HEAD than

recorded in the index

m the submodule has modified content

? the submodule has untracked files

since modified content or untracked files in a submodule cannot be added

via `git add` in the superproject to prepare a commit.
|

'm' and '?' are applied recursively. For example if a nested submodule
|

in a submodule contains an untracked file, this is reported as '?' as well.
