I was apparently wrong about that last statement (and so too about
the first statement, that in 24.3 the function accepted only two args).

[However, I do not really understand, and have no time to research
this now: in Emacs 24.3, emacs -Q, `C-h f kill-region' does NOT
show parameter YANK-HANDLER.  But in the 24.3 source file simple.el,
YANK-HANDLER is present.  Perhaps the simple.elc distributed by GNU
is older than the addition of YANK-HANDLER to simple.el?]

The NEWS entry should state not that the YANK-HANDLER parameter
was removed but that it was replaced by the REGION parameter etc.

And of course there SHOULD have been a NEWS entry for 24.3,
stating that parameter YANK-HANDLER was added.  If it is not too
late, that should be added now.  Without it, mention of YANK-HANDLER
in the 24.4 entry makes no sense.
