Checkin release notes
Avoid duplicate entries on find/replace pasteboard
Add CoreData index to pasteboard entry content

If any folding pattern is set as a scoped setting, use it

Previously we would fallback on the grammar’s folding patterns unless ‘foldingStartMarker’ was set, which meant setting just the stop marker or indented folding patterns, would be ignored.
