pub fn is_mode_change_only(line: &str) -> boolExpand description
Detects if a diff section represents a mode-only change (no content changes).
Mode-only changes have lines like:
- “old mode 100644”
- “new mode 100755”
This function checks for the “old mode” marker which indicates a mode change. A mode-only change is one where only the file permissions changed, not the content.
Requirements: 4.4
