bug#29013: 25.3; [wishlist] do not yank whitespace

[Alex Branham]

It would be nice to have an option so that yank never returns pure whitespace. The current behavior is such that if we have:

#+BEGIN_EXAMPLE
some text here

some text there|
#+END_EXAMPLE

with | representing where point is, if you execute C-SPC C-a M-w C-p C-k C-p C-y then you end up with:

#+BEGIN_EXAMPLE

some text here
some text there
#+END_EXAMPLE

but I would like to end up with:

#+BEGIN_EXAMPLE
some text there
some text here
some text there
#+END_EXAMPLE

Thanks,
Alex

Just type M-y (yank-pop) to get the next element from the kill ring.
You can also use DEL to delete the empty line without polluting the kill
ring.

Thanks for the response.

Yes, I know I can work around this. However, I rarely (if ever) want to yank pure whitespace. It'd be nice not to have to think about it.

I think that's a good idea -- or, to be more general, I think it would
be nice if there was a way to transform texts before they're put on the
kill ring, and possibly discard them.

So for this particular use case, the transformation function could
return nil to indicate that it shouldn't land in the kill ring.

So I've now added this to Emacs 28 under the name kill-transform-function.
