This commit teaches 'git commit/status' show 'Modified submodules'
section given by
git submodule summary --cached --for-status --summary-limit <limit>
just before 'Untracked files' section.
The <limit> is given by the config variable status.submodulesummary
to limit the submodule summary size. status.submodulesummary is a
bool/int variable with value
- false or 0 by default to disable the summary or
- positive number to limit the summary size or
- true or negative number to unlimit the summary size
Also mention status.submodulesummary in the documentation.
