I'm generally not in favour of new ini settings. I also don't think this=20

But, I am especially not keen on "negative names". Names that include=20
"ignore" or "disable" for example. If you must have an ini setting, it=20
ought to be something like "include_error_args" (defaulting to "0", I=20
suspect).
