Of course. But note that I said "reference documentation". It is quite frequent that you have read it a long time ago, or understand already most of what it is saying, and you are re-reading it again looking for rules about a _specific_ element (say, wildcards). You might not have just now read the bit about disambiguation, but you do not need to; you already know it, or it might not be relevant to what you are doing. > The second and the third one are related in the "sides of the same > coin" sense; you either have "--" in which case no disambiguation > checks are done, or don't in which case your command line may get an > ambiguity error, so in that sense, you could say "I am writing '--', > so point C does not apply to me and I skip".

Sometimes people will sit down and read all the way through, and we need the text to flow and make sense for that case. But just as often, they will be curious about one specific point, and we need to make it as easy as possible for them to see when a new point is being made, and when they can stop reading because they have wandered into a new point that they may already know. Which is why I think the best thing we can do for such a casual reader is make sure that the typography helps group related text together. In this specific example, imagine I am a seasoned Unix user and a new git user. If I were reading about "--" and revs versus paths, that would be news to me, because it is about git. When I see the next bullet is about quoting "*" to pass it through the shell to git, I say "Of course. That is how Unix shells work" and stop reading. It seems like a disservice to the reader to include more on the "--" disambiguation _after_ that bullet point. > So I do not think a bullet list is designed to let the readers skip > and forget (or "may not even have read").

As a tool for people reading the whole text, I think the list is a bad format, since the elements do not follow a good parallel structure (as you said, the second and third are much more related than the first and fourth). So I was tempted to suggest removing the list altogether and turning it into paragraphs. But as I said, I think breaking the points with whitespace helps the casual reader using it as a reference. I'm not sure you agree, but maybe what I've written above will change that. If not, I think I've said as much as is useful on the matter and I'll stop talking. :) > I think the following is probably the best. > > * A (revs and then paths) > * B (with "--", no dwim is done). > * C (without "--", disambiguation kicks in.

Hmph. Isn't that what I suggested in my first email? :P I am fine with the series you sent. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
