patches: fix commit msg line lengths, add remaining fixes

- 0007/0008: rewrap long commit message lines (>78 chars created by
  package name generalization); Emacs commit-msg hook enforces 78 char
  limit
- 0006: add paragraph break before 'Block-style cursors' sentence in
  macos.texi VoiceOver section; update hunk count accordingly
- 0000/0007: add comment documenting intentional ns_zoom_face_is_selected
  / ns_ax_face_is_selected duplication (independent series design)
