It would be quite useful if one can actually *undo* edits in the pp
buffer.

Background:

I am examining a deeply nested list as shown below.

  (pp-display-expression deeply-nested-list "*deeply-nested-list*")


Often times I find myself editing/re-adjusting the pp display buffer to
make sense out of what is in there.  I also find myself undoing edits to
that buffer.  This is when the following user-error is thrown.

  user-error: No undo information in this buffer
