• Single area: +10 (+15-5) - Shows net changes with add/delete breakdown
• Multiple areas: Staged:+2 (+5-3), Changes:+8 (+10-2), Total:+10 (+15-5) - Shows each area with add/delete breakdown
• Clean: Clean - No changes

Examples:

• $(git-commit) +10 (+15-5) (single area with changes)

Changes: +8 (+10-2)
  +8 (+10-2)=300 [New] fileC.py
