Forcing the synchronization of 500 lines is both slower and less precise than searching for a known sync point. Unfortunately, though, the way to synchronize correctly is using the grouphere instruction, which has a bug. I've already proposed the fix to Vim, so future releases should have this working. We can continue using the 500 lines syncing for now. This change just documents the proper way to sync. R=adg, dsymonds CC=golang-dev https://golang.org/cl/4029047
