I noticed this because when I was creating a local version of the cloc v1.80 binary to test against at https://raw.githubusercontent.com/gshuflin/binhost/master/bin/cloc/1.80/cloc , I was hitting that error in

fetcher.py

, and also my browser was doing gzip compression and had a

Content-Length

header about 1/5 the size of the actual downloaded binary
