 Key:
 - std format      - the error message follows a standard format (location on first line, megaparsec-like excerpt, description).
-- line            - the optimal line(s) is(are) selected
-- column          - the optimal column(s) is(are) selected
-- excerpt         - a useful excerpt is shown (Y), ideally with the error highlighted (YY)
-- flycheck        - latest flycheck release recognises and reports the error, with no "suspicious state" warning
+- line            - the optimal line(s) are reported
+- column          - the optimal column(s) are reported
+- excerpt         - a useful excerpt is shown, ideally with the error highlighted (✓✓)
+- flycheck        - the current flycheck release recognises and reports the error, with no "suspicious state" warning
 - flycheck region - flycheck highlights a reasonably accurate region containing the error
