fatal error in Buffer.undone reading inserted contents: EOF

[rjkroege]

Fatal crash. Not nice. Replicate:

• create a buffer with New
• paste a bunch of text
• Do a large Edit op
• Undo

@camsn0w did you ever see this?

[rjkroege]

Seems to be on the first delta. The second change is correctly undoable. It also seems to require the use of Edit.

This looks like a duplicate of #467, with a bit more repro context.

[rjkroege]

Yes. Definitely #467.
