[PATCH 0/1] Fix netrc usage with WebDAV-based HTTP protocol

For a long time, we've enabled the automatic usage of netrc if the user doesn't provide any credentials. Unfortunately, in 2.46, this broke for the WebDAV-based HTTP protocol, which this series fixes.

In looking at this issue, I discovered that we have (before this series) zero tests for the netrc functionality and zero documentation for it, which obviously is suboptimal. In this series, I am adding one test, which is for this particular bug.

However, I think we need to either decide that we're going to support this as a fully-fledged feature and add documentation and sufficient tests, or remove it, since it's not reasonable to have undocumented, untested features that people rely on. Our HTTP code is quite subtle and complex and we can't expect future developers not to break things in this state[0]. I will note, as an argument in favour of removal, that we have git-credential-netrc helper in contrib that users can enable if they want to retain this functionality, and we could even ship it by default without much difficulty. For those reasons, I am not planning to add more tests and documentation here, but of course I welcome interested parties to do so.

[0] Personally, I had some vague knowledge this feature existed and I feel like I'm reasonably familiar with the HTTP code, and I still accidentally introduced a bug, so that doesn't bode well for contributors who are less familiar with it.
