Nothing for the advice of `redisplay-(un)highlight-region-function' or `region-extract-function', or for those variable themselves, or for the functions used to advise them (`rectangle--highlight-for-redisplay', for example). Nothing for `redisplay--update-region-highlight(s)', or other funtions that use those `*-function' vars, or for `pre-redisplay-function', which uses `redisplay--update-region-highlight'. IOW, nothing for anything that does region (un)highlighting redisplay, including `deactivate-mark' (which has a doc string, but whose doc string does not cover this new part of its behavior). None of the so-called "New rectangle integration with kill-ring" behavior is documented in doc strings. It is also not documented in NEWS, AFAICT. This code change represents a change in user-visible behavior, and it should be documented. [It's a shame that Emacs Dev has increasingly neglected to add helpful doc strings (IMHO). The originator of the self-documenting editor is no longer watching closely, and developers will be developers, I suppose... Too bad. BTW, why is Emacs code simply using `add-function' all over the place now, instead of actually adding the code to the functions? Is advice the new normal for Emacs code maintenance?] In GNU Emacs 24.4.50.1 (i686-pc-mingw32) of 2014-06-28 on ODIEONE Bzr revision: 117431 rgm@gnu.org-20140628015517-eku6hj8mpgcvfnso Windowing system distributor `Microsoft Corp.', version 6.1.7601 Configured using: `configure --prefix=3D/c/Devel/emacs/snapshot/trunk --enable-checking=3Dyes,glyphs 'CFLAGS=3D-O0 -g3' LDFLAGS=3D-Lc:/Devel/emacs/lib 'CPPFLAGS=3D-DGC_MCHECK=3D1 -Ic:/Devel/emacs/include''
