[PATCH] www_listing: fix manifest.js.gz generation with extindex "all"

[PATCH] www_listing: fix manifest.js.gz generation with extindex "all"

[Eric Wong]

WwwListing and ManifestJsGz may be too different nowadays to
be worth the code sharing between them.

Update some comments and note we still needs better tests :x

Fixes: 520be116e8a686cb ("www_listing: start updating for pagination + search")
