Re: Should text-scale trigger hooks?

[James Cherti <contact@jamescherti.com>]

I tested adding a function to `text-scale-mode-hook` that executes:
(run-hooks 'window-configuration-change-hook)

And it solved the issue in both packages (`eat` and `visual-fill-column`).

After further consideration, I believe that this is not an Emacs core 
issue, but rather a problem caused by the implementation of those 
packages. It doesn't make sense for text scaling to run the 
window-configuration-change-hook functions.
