Merge branch 'sb/submodule-path-misc-bugs' into sb/submodule-init

"git submodule" reports the paths of submodules the command
recurses into, but this was incorrect when the command was not run
from the root level of the superproject.

Any further comments?  Otherwise will merge to 'next'.

* sb/submodule-path-misc-bugs: (600 commits)
  t7407: make expectation as clear as possible
  submodule update: test recursive path reporting from subdirectory
  submodule update: align reporting path for custom command execution
  submodule status: correct path handling in recursive submodules
  submodule update --init: correct path handling in recursive submodules
  submodule foreach: correct path display in recursive submodules
