Merge branch 'gr/add-e-use-apply-api' into seen

The application of the edited patch in 'git add -e' has been
refactored to use the internal apply API directly, avoiding the need
to spawn a 'git apply' subprocess.

* gr/add-e-use-apply-api:
  builtin/add.c: replace run_command() with direct apply_all_patches() call
