git clone
writes its output to stderr
as documented here. I can redirect this with the following command:
git clone https://myrepo
I just wanted to add that if, like me, you were more concerned with getting errors-and-only-errors in stderr and didn't care about progress either way, then there's a dead-simple workaround - you can just add --quiet (or -q) to the command.
This tells git to simply stop reporting progress at all unless an actual error occurs.
