Lots of changes since v3 (well more than between v2 and v3). Thanks for all of the reviews on the last round, the series is getting more polished. * Eliminated the "# service" line from the response from an HTTP server. This means that the response to a v2 request is exactly the same regardless of which transport you use! Docs for this have been added as well. * Changed how ref-patterns work with the `ls-refs` command. Instead of using wildmatch all patterns must either match exactly or they can contain a single '*' character at the end to mean that the prefix must match. Docs for this have also been added. * Lots of updates to the docs. Including documenting the `stateless-connect` remote-helper command used by remote-curl to handle the http transport. * Fixed a number of bugs with the `fetch` command, one of which didn't use objects from configured alternates.
