• File internal/repo/setting.go — part of check-in [430dd5ec70] at 2026-10-20 01:49:55 on branch fix/cli-path-matching — fix(cli): match PATH as fossil does; run pragmas in a fixed order

  log --path, cat --at and diff drop a leading ./, a trailing / and doubled or /./ separators, and compare names with the repository's case-sensitive setting, fossil's platform default when unset. Not found stays exit 2, where fossil exits 1; the docs now say so. SettingBoolean moves to internal/repo, shared by sync and checkout.

  Opening a repository runs every pragma in a fixed order, not only busy_timeout first.
