While we already have a porcelain2 layer for git-status, that is accurate
for submodules, users still like the way they are are used to of
'status -s'.
As a submodule has more state than a file potentially, we need more letters
indicating these states, we'll go with lower 'm' and single '?' for now.
When there the recorded commit doesn't differ from the submodule HEAD
(which we still want to treat as "M", because that can be dealt with
in the superproject), we can have different types of change in the
submodule. The lower case 'm' indicates that there are changes to tracked
files in the submodule. It signals that the --recurse-submodules option
is needed for e.g. adding or committing these changes. The " ?" also
differentiates an untracked file in the submodule from a regular
untracked file.
While making these changes, we need to make sure to not break porcelain
level 1, which uses the same code as the short printing function.
