Makes sense. This should have been done as part of b831deda (2010-06-01), but better late than never. Let's see how the patch goes...

Git commands consistently accept a tag pointing to a commit where a commit is expected, so emphasizing that feature by calling it a commit-ish only adds distraction. That's not what this patch is about, though. Even for this particular form, the current file is inconsistent about whether to call the arguments '<paths>...' or '<pathspec>...'. "<paths>..." is even more strange when I think about it for a moment, since it is the plural of the plural of path --- i.e., it implies that each argument names multiple paths. Why does this patch use <pathspec> for the --no-patch case and <paths> for the --patch case? > DESCRIPTION > ----------- > @@ -78,20 +79,13 @@ be used to detach HEAD at the tip of the branch (`git checkout > + > Omitting <branch> detaches HEAD at the tip of the current branch. > > +'git checkout' [<tree-ish>] [--] <pathspec>...:: > + Restore modified or deleted paths in the working tree by > + replacing with their original contents from the index, or > + the contents from a named <tree-ish> (most often a This sentence is hard to read: - "Restore ... in" reads oddly, as though this is an art conservation project that takes place in the working tree. Is the intent that the command will bring the content of those paths back to the working tree, or something else? - "replacing with" reads a little briskly and informally. In this context, "replacing them with" will work better. - "their original contents from" also reads oddly. "Their original content from" would be fine, meaning their original content as obtained from. I was tempted to read this as "The original contents of", but that was a misreading. - Similarly, "the contents from" perhaps should be "the content of". Stepping back, what problem is this solving in the original text? It said When <paths> or --patch are given, git checkout does *not* switch branches. It updates the named paths in the working tree from the index file or from a named <tree-ish> (most often a commit). In this case, the -b and --track options are meaningless and giving either of them results in an error. The <tree-ish> argument can be used to specify a specific tree-ish (i.e. commit, tag or tree) to update the index for the given paths before updating the working tree. The "or --patch" would have to go, of course. Is the problem that the description focuses too much on what this form does not do? To fix that, it could say Replace matching paths in the working tree with content from the index or the named tree (most often a commit). The <tree-ish> argument can be used to specify a specific tree, commit, or tag that will be used to update the entries for matching paths in the index before updating the working tree. One thing that doesn't tell is what happens to files that are present in the worktree but deleted in the index or the named tree. Does "git checkout" delete them? I remember wishing that it would but don't remember whether it does, so it's probably worth mentioning the manpage giving an answer. ... aha, now I see the next paragraph where this text came from. I still think I like my example text based on the first paragraph better. :) [...] > @@ -101,6 +95,14 @@ specific side of the merge can be checked out of the index by > using `--ours` or `--theirs`.

The options section explains --patch again. Maybe that should point back to here to avoid some duplication. Thanks, Jonathan
