Privacy, accuracy and limitations
- Exact matching: capitalization, spaces and punctuation are significant.
- First occurrence kept: later identical lines are removed without changing the initial order.
- Blank lines: multiple identical empty lines are reduced to one empty line.
- One line per item: entries containing internal line breaks are treated as separate values.
