RFE: (chorded) cut followed by a paste in the same spot should leave the file unchanged

[siebenmann]

This is likely to be low priority.

I believe that one of the things Rob Pike has mentioned he did with chorded cut & paste in acme is make it so that if you cut and then immediately pasted the cut back in the same spot, the file was considered unchanged. The advantage of this is that you get a clean chorded 'snarf' operation, instead of marking the file as dirty (and making sam complain if you don't write it out sooner or later and so on).
