In the patches for CVE-2020-11008, the ability to specify credential settings in the config for partial URLs got lost. For example, it used to be possible to specify a credential helper for a specific protocol: [credential "https://"] helper = my-https-helper Likewise, it used to be possible to configure settings for a specific host, e.g.: [credential "dev.azure.com"] useHTTPPath = true Let's reinstate this behavior. While at it, increase the test coverage to document and verify the behavior with a couple other categories of partial URLs.
