I've been following a guide on the deflate algorithm (because I wanted
one where I could control how memory is allocated just as Lua allows)
and found when I put this:

echo "hello hello hello hello" | gzip

into the terminal gzip incorrectly set the NAME flag, it was only
after editing it out I was able to deflate the resulting file, the
same applies for this:

echo -n "abaabbbabaababbaababaaaabaaabbbbbaa" | gzip

Both of which are the examples given on
https://blog.za3k.com/understanding-gzip-2/
