Yes, I've observed that by now; it's just the nitpicking perfectionist
minimize-unnecessary-effort part of me which complains. (Because I *had*
seen the patch on the list, and comments thereon; I just hadn't gone
through to add my own.)

Probably, since that is AFAICT the technically correct form. The fact
that it is the expansion of a well-known acronym helps with grouping in
that respect, however, and might qualify it for an exception.

In any case, I did note that this was arguable; I leave the decision to

That works, and has the advantage of being more clear; now I actually
understand what it's talking about. <grin>

I still think you need a comma before the "but", but this is otherwise

Part of the problem is that I don't know exactly what the option does
(which probably just means that this *does* need to be rephrased)... my
first thought is to say "without adding any delay", or something
similar, but I don't see how that makes any sense from a technical

That's fine for the first sentence, but IIRC I included the second
because it is also not quite right, and this doesn't change that.

How about something like "Whether or not the use of this option will
save bits is highly dependent on the source material."? That's still not
perfect, but I think it's better.

As far as I could tell... the first part I couldn't tell, the
interviewer was the type of Hispanic whom I find almost unreadable. The
second part, however, seemed to go fairly well, and they tell me I'll
know one way or another by early in the week (possibly even Monday).

I used my activity, such as it is, on these lists as part of my
credentials... I was pleased to note that one of the people, at least,
did appear to have heard of MPlayer. <grin>

Quite true, but at the time I wrote that, it had slipped my mind that
what I was commenting on was the man page. <grin>

Yes, acknowledged, and in fact I knew it already; the paragraph was
mainly for the sake of the completeness of this set of comments.
