Right.  I do not recall seeing anybody doing a deep dive, which I
would prefer to see done in the code paths involved.  At least I'd
want to see somebody (could be me) verify that the changes would not
break when the new option is not in effect before merging it.

Oh, no quiestion about that part.  Otherwise we wouldn't be listing
the topic in this list ;-).  I just want to see support not just by
the end-users who do not know or care how the thing looks internally,
but also by the folks around here who do.

Thanks.
