Use an IPv4 loopback redirect URL instead of the
localhost
name. This is in accordance with the recommendation in the OAuth spec12 and also GitHub's documentation3.Note that this change depends on an update to the Git Credential Manager OAuth application on GitHub to add the "http://127.0.0.1/" redirect (with a trailing slash!). We will be strictly adding the new URL, and keep the older localhost-based redirect URL untouched for older clients.
The change to the OAuth app registration can occur before this is merged.
Fixes #594
