Replacement callback, row-based filtering, and revision exclusion

[drzraf]

Replacement callback & row-based filtering (include/exclude posts revisions)

• Replacing revisions is confusing (total replacements count) and annoying
• Specifying rows/columns/custom --where expression has been a long requested feature (for more than 8 years)
