Doesn't the -A zip cause it to skip the subpages? That's what I'm saying...the filter is keeping you from traversing main page -> sub page -> zip file.
No if you check the output, or even enable -d, you'll see that it goes through sub-pages. It downloads all the index files into a tmp file so it can parse them for more sub-pages, then deletes them after because they don't match the pattern.
It even goes as far as to download download.damieng.com/fonts/conversions/Micropack.zip, proving that it does traverse domains and sub-dirs, but nothing under download.damieng.com/fonts/zx-origins.
It's really strange, I'm thinking it has something to do with all the .zip archives being linked without a protocol (//download.damieng.com), might be a bug but I'd be shocked if no one had encountered it before.
