Ensure window-end is up-to-date for all ace-link functions

[LemonBreezes]

Hi. In my previous PR, https://github.com/abo-abo/ace-link/pull/83, I addressed an issue where the Avy background was not extending across the entire window for ace-link-man. Now I am having that issue for ace-link-w3m as well. As a fix, I have patched herein all ace-link--*-collect functions so that they use the correct end value.
