The init file reads past a UTF-8 BOM, and every line it fails is said and logged with its line number, never silent

A BOM made the first word unknown, a word no builtin has was skipped
without a word, and a setting that refused its value said nothing (the
init file ran with announcing off). Each failing line now leaves a
notice and an `err - init file line N: <why>` record; `#` still starts
a comment only at a line's start, so `#ff0000` stays a value.
