-- Unit checks for custom/extensions/link-commits.lua, run under a standalone
-- Lua by t0503-link-commits.sh with the script path as the argument. The
-- shipped configuration links bare object names to ./?id= and issue marks
-- like #123 to bugs.example.com, and everything here checks that shape, the
-- length bounds and frontier on hash recognition, and the rule that no run
-- of text is ever wrapped twice.
