Re: C-x C-v considered harmful

[Richard Stallman]

       But I am really curious to know why Richard changed this in rev 1.192
    to the current (and (buffer-modified-p) (buffer-file-name)) behavior.
    Richard, do you remember?  I know this is asking a lot . . .

I don't remember, but I would guess it is becuase most non-file-visiting
buffers don't contain precious information.  I probably did not think
about the cases where they do.
