This is all on the wrong track, I tell ya.  A Hack philosophy.  You've
got a key that is doing different things depending on the read-only
status of the buffer.  Do nine instances of using C-k to "save line as
killed but don't kill it" in read only buffers, and then I give you a
read-write buffer and you'll certainly take the ease of C-k [C-k...] C-y C-x
C-s over the fuss of C-@ C-e M-w C-a, especially when you've already
been habituated that all one needs is C-k [C-k...] and not even the
C-y C-x C-s.

So you get "Jones, why every time I ask you to look around in that
file, you insist on writing it again to disk?"

So instead on introducing this schizophrenia with one key doing
different things, I say add a "non damaging kill-line" that works the
same regardless of what the read-only flag is set to.

yup, so along with 'buffer modified' one starts making #backups#, and
then the file date gets rewritten, and it becomes a weekly backup
candidate, etc.
