-- Unit checks for custom/extensions/link-trailers.lua, run under a standalone
-- Lua by t0506-link-trailers.sh with the script path as the argument. The
-- shipped configuration links Fixes and Reverts object names to ./?id=,
-- Closes and Bug marks to bugs.example.com and a bare URL to itself, and
-- everything here checks that shape, the key matching and the values that
-- must pass through untouched.
