wget -c https://swscan.apple.com/content/catalogs/others/index-10.13-1.sucatalog.gz

This url points to an xml file, even if it has a gz extension.

file index-10.13-1.sucatalog.gz
index-10.13-1.sucatalog.gz: gzip compressed data, was "index-10.13-1.sucatalog.nk11p01su-swupdate002.isu.apple.com.gzt", last modified: Tue Oct  3 12:20:56 2017, from Unix

Sorry my mistake, it is indeed a gz. Safari opened it like the xml it contains, that confused me. But it has the magic number 1F8B.

Technically this is not wrong, since it's applying the original filename. The other apps are just ignoring the original name.

Here I've stripped the original filename data, so it just names the content as the gz file:

index-10.13-1.sucatalog.gz.zip

I don't think this is something to be changed. If the package creator included the original filename, it must be replicated.

I'm seeing at least GNU Gzip always stores the original filename but only uses it if -N flag is used, so by default does not restore the original filename.

This will be available using setting the option IgnoreGZIPName in next 1.2.0 revision.
