Distinguishing this from the OR operator requires matching with the previous statement terminator which may be several lines earlier. There is unlikely to be more than one blank line, or any line comments, before the OR but let's set syn-sync-minlines to 5 to allow for a buffer during editing.

parallel in 2022 will require similar handling and at which point the name will need to be further generalised anyway.
