The 2nd patch of v2 are splitted to 2 patches in v3 (the 1st and 3rd one)
to support bool/int behaviour of status.submodulesummary.
The other 2 patches are the same as v2.
Ping Yin (4):
config.c: Add git_config_bool_or_int to handle bool/int variable
git-submodule summary: --for-status option
builtin-status: submodule summary support
