Relative links and images in issue, comment and proposal text resolve against the repository's default bookmark, and in release notes against the release's tag. Cross references: `#12` links an issue or proposal; `owner/name#12` across repositories; a 12-hex-or-longer token links a change when it resolves; `closes #12` in a change message closes the issue when the change lands on the default bookmark ("closed by change"). Any other `#12` in a pushed change's message, on any bookmark, puts "referenced by change <hash> on <bookmark>" on that issue's or proposal's timeline, the hash linking to the change; other repositories' `owner/name#12` are left alone.
