Yes, my failure. Looking at the code, the regex options are applied
without taking --recursive or --level into account. They are dumb URL

We are back at

wget -d -olog -r -Dcomicstriplibrary.org -A "*little-nemo*s.jpeg"

that doesn't work as expected. Somehow it doesn't follow certain links
so that little-nemo*s.jpeg files aren't found.

Interestingly, the same options with wget2 are finding + downloading
those files. From a first glimpse: those files are linked from an RSS /
Atom file. Those aren't supported by wget, but wget2 does parse them for
