[Bug-wget] Some URLs are saved as gzip-compressed data

[mark_k]

I'm testing wget 1.20.1 on Lubuntu 16.04 x86-64.

I noticed an issue when trying to download a certain URL which is
a .zip archive. The file created by wget is gzip-compressed. But
downloading using e.g. Firefox the URL is saved as a .zip file.

Example:

$ wget
