Changes from v4: * Fix several commit message to fix typos and inaccuracies. * Remove useless touch statement in tests. * Adjust several tests to introduce less dependence on previous test assertions other than the setup ones. * Loosen the regexp for object IDs in a Perl script in a test. * Ensure help functionality works for git http-fetch. * Switch http-fetch.c to use the already existing struct argv_array instance. * Avoid a memory leak, albeit a minor one. * Improve error message for unknown bundle hash algorithm. * Hoist a strbuf_rtrim in the bundle parsing code to simplify things. * Specify a minimum version instead of a default version in the bundle code. * Remove a useless line in tests. * Avoid invoking git hash-object needlessly for the SHA1 prerequisite. * Be explicit about which algorithms we're testing in CI. * Properly capitalize "core.repositoryFormatVersion" in documentation. Changes from v2: * Move bundle signature parsing into a function. * Improve parsing of bundle capabilities. * Improve t5510 to select only the interesting lines with sed. * Use cat and a heredoc instead of multiple echos. * Use test_i18ngrep where appropriate. * Reject extensions.objectFormat for repo v0. * Update documentation accordingly. Changes from v1: * Add a patch to add a bundle v3 format with capabilities that include the hash algorithm. * Remove bundle detection of hash algorithm using hash algorithm length. * Fix typo in the extensions.objectFormat documentation. * Document that extensions.objectFormat is ignored for repo v0. * Use test instead of brackets. * Use a command group instead of a subshell for efficiency. * Drop the bizarre test_might_fail, since it isn't needed (and is bizarre and wrong). * Write "SHA-256" instead of "NewHash" in commit messages. * Split SHA-256 CI tests to an independent run and avoid running a third test run to a single CI job.
