[PATCH 0/2] bug fix with push --dry-run and submodules

[Brandon Williams <bmwill@google.com>]

While trying to understand how the recursive pushing of submodules worked I
discovered that when push was instructed to do a dry-run, while also configured
to push unpushed submodules 'on-demand', that the submodule pushes weren't
configured to perform dry-runs, but actually performed the pushes.  This
resulted in the submodules being pushed while leaving the superproject unpushed
which is undesirable behavior for a dry-run.

This series introduces a test to illustrate the bug as well as a patch to
correct this behavior by passing the --dry-run flag to the child processes
which perform the submodule pushes during a dry-run.

This series is based against 'origin/hv/submodule-not-yet-pushed-fix'

  push: --dry-run updates submodules when --recurse-submodules=on-demand
  push: fix --dry-run to not push submodules
