Following patches will teach git-submodule a new subcommand 'summary' to
show commit summary of user-cared (i.e. checked out) submodules between
a given super project commit (default to HEAD) and working tree
(or index, switched by --cached).
This patch just introduces the framework and find submodules which has
summary to show. A submodule will have summary if it fits into any one of
following cases.
- type 'M': modified and checked out (1)
- type 'A': added and checked out (2)
- type 'D': deleted
- type 'T': typechanged (blob <-> submodule)
Note:
1. There may be modified but not checked out cases. In the case of a
merge conflict, even if the submodule is not checked out, there may
be still a diff between index and HEAD on the submodule entry
(i.e. modified). The summary will not be show for such a submodule.
2. A similar explanation applies to the added but not checked out case.
