I think your conclusion is true, but as for the proposition (people type
parens one by one), I think most people simply don't end up with this pattern
of parentheses when they code lisp. Where did the newline come from
anyway, especially since it is not desired ?

However, I would probablly use this baby :


,----[ C-h k M-^ ]

| Join this line to previous and fix up whitespace at join.
