previewCursorScope was sort of a failed experiment

moving the cursor around had strange behavior when the only characters on a line were close-parens

it didn’t feel right to have these visual indicators of scope follow the cursor around in the form of text that you couldn’t for example type after. it created a frustrating experience

what really sealed the deal in its removal was that it conflicted with how i resolved the leading close-paren problems—by running paren-mode when they were present

besides, I really want indent guides to serve the use-cases that previewCursorScope was intended to solve
