[coderobe]

Change Description

A user agent that doesn't respect hsts could potentially be coerced into downloading malicious sources for wabt via a mitm attack. Prevent this by using a https upstream like the other submodules already do

This is good but I assume it only works for fresh clones? Even after checking out your branch, doing a submodule deinit+init+update, my submodule still seems to be using http. Do you know of a good & proper way to update this in place too?

[coderobe]

You can probably change this in-place using git config, the config key on the submodule is url.

@coderobe can you rebase this on develop please?
