Fix error-related issues (#773)

Browse Source 
* Mark `error` as a `format` function, to properly scan its format

* Fix the call to error() from parser.y:
  - Use '%s' to avoid passing an arbitrary format
  - Simplify yyerror overall

* Fix size parameter of %.*s format being an int... bonkers standard.

* Report the number of arguments required and provided on a STRFMT mismatch

* Add an assert to check for a very unlikely bug
