Care to elaborate?
As in my example, git clone --branch <branch> does not accept all of (3). I now see that indeed the options section for git clone --branch has been changed to inlude the information that tags are also allowed, so that's in order. > Outside "git checkout", we historically deliberately stayed loose in > an attempt to help beginners by avoiding <committish> or <ref>, when > most people are expected to feed branch names to the command and > used <branch>.

If I understand you right, the Synopsis and description are supposed to explain the non-hackish usage of commands, whereas documentation after the OPTIONS headline is supposed to be more of a complete description. Hence e.g. the synopsis of git-checkout does not mention the --t,--track,--no-track options, and takes a liberal approach to option syntaxes (listing '[-p|--patch]', but only '-m', but not '[-m|--merge]'), similar git-clone help does not mention the '--branch' option in the synopsis for that reason, I guess. Do I get this right? Does this also extend to the (bash) tab completion? E.g. hitting tab after "git clone --", offers me (Ubuntu precise, git 188.8.131.52): --bare --local --no-checkout --origin --reference --template= --depth --mirror --no-hardlinks --quiet --shared --upload-pack missing: ---recursive --recurse-submodules (--[no-]single-branch) --separate-git-dir --verbose --progress --branch Is this also intentional? cheers, Thibault -- 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
