Re: Run `window-configuration-change-hook` in Lisp code?

[James Cherti <contact@jamescherti.com>]

Thank you for confirming that you would place it in the
'bad practices' column.

Yes, the patch works; however, I closed the pull request as
it was too specific to another package I'm using, which restores
persisted text scale through a hook in
`window-configuration-change-hook`.

In the general case, however, the need to run
window-configuration-change-hook during text-scale-mode-hook
is not particularly important.
