Hi, thank you for your PR. It appears that since LuaRocks 3.8, git://github.com URLs are automatically converted: luarocks/luarocks@9ff512e, so there is not an immediate need for a fix.

Did this change work for you? I would expect it to fail, shouldn't the scheme be git+https instead of https? From https://github.com/luarocks/luarocks/wiki/Rockspec-format#user-content-build_rules:

git:// - for the Git source control manager
git+http:// - for the Git source control manager when using repositories that need http:// URLs
https:// - for HTTPS URLs

Aside from that there are some typos in the commit message.
