For multi-modes representing dynamically generated content (PHP +
HTML, etc.) there's going to be fragments that will be hard or
impossible to indent meaningfully. Can't be avoided, I think.

What about code that deals with the buffer's major-mode? In a PHP +
HTML buffer, or a Literate Haskell source (assuming it's a multi-mode
buffer with text and Haskell submodes), what will (with-current-buffer
"my-multi-buffer" major-mode) return? Does it depend on `point'? If
you switch the buffer's major-mode, does it change for all fragments?
