Since --git-user is a user-facing name, it's common to include a space
in it. As such, it's not suitable to use as a username in a Git remote
URL.
GitLab documented that it doesn't (yet?) check for username [1], and
from my testing GitHub doesn't seem to care either. So just use an
arbitrary name as a username.
