Mg v3.7

Changes

• New command display-help-toggle, ensures the quick-help text is
  always shown in the status area, enabled by default
• New command apply-macro-to-region-lines by Ben Scuron
• New command end-or-call-last-kbd-macro, used in key bindings
• Map function keys F1-F4 + F10 to common functions:
  • F1: Toggle quick help
  • F2: Save current buffer
  • F3: Start keyboard macro
  • F4: End keyboard macro, or call latest macro from mark
• Sync with OpenBSD as of April 21, 2023:
  • Add command set-tab-width to change per-buffer tab width
  • Sync manual changes: grammar, visual improvements
• Drop support for disabling no-tab-mode when calling configure
  script. Simplifies code greatly and not needed anymore since it is
  enabled by default upstream
