[Message part 1 (text/plain, inline)]

The hook `window-size-change-functions' is not executed when a frame is
manually resized.

In Emacs 23 it was called, but in Emacs 24 and Emacs 25 it isn't.

For example, this break the package Follow mode, its windows are not
aligned after the frame has been resized.

If no one objects I intend to install the attached patch on Emacs-25.
Anders please confirm that it fixes the problem.

Thanks, martin

Hi!

I can confirm that this works. I tested both the simple example I posted in
the original bug report and also with follow mode.

Thanks!
