These patches teach git-submodule a new subcommand 'summary' to show
commit summary of checked out submodules between a given super project
commit (defaults to HEAD) and working tree (or index, when --cached is
given).
This patch just introduces the framework to find submodules which have
summary to show. A submodule will have summary if it falls into these
cases:
- type 'M': modified and checked out (1)
- type 'A': added and checked out (2)
- type 'D': deleted
- type 'T': typechanged (blob <-> submodule)
Notes:
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.
