I'd also write `refs/tags/`, but I realize that you're just inheriting what is already here. If you'd rather punt on that, that's understood. This whole document could need a look-over with respect to monospacing anyway, but it seems unfortunate to introduce *new* non-monospaced instances, especially for command-line options where it's pretty clear how they should be handled (Documentation/CodingGuidelines, line ~610). > ++ > +With --ff-only, resolve the merge as a fast-forward when possible > +(when the merged branch contains the current branch in its history). > +When not possible, refuse to merge and exit with a non-zero status. > ++ > +With --no-ff, create a merge commit in all cases, even when the merge > +could instead resolve as a fast-forward. > ++ > +With --ff, resolve the merge as a fast-forward when possible.

I was sort of expecting these to be listed in the order "--ff, --no-ff, --ff-only", and I see Sergey suggested the same ordering. The way your proposed text reads does make sense though... Would it read as well turning it over and going through the options in the other order? That's the way it is before your patch, so you could argue "but people don't grok that!". What your patch does well is to offer an overview before describing each option in a bit more detail. Would that work with the reversed direction as well (compared to this patch)? Dunno. I wondered briefly whether it might make sense to float "The default is `--no-ff`." to the top, but since it's really "The default ... unless so-and-so", it would probably complicate things more than it'd help.
