The intention to remove non-option from the OPTIONS enumeration, and to explain <new> and <old> used as arguments to -m and -c where these options are described, are both very good (heh, after all, they are parts of what I envisioned to be the way to go in the longer term ;-). > overridden by using the `--track` and `--no-track` options, and > changed later using `git branch --set-upstream-to`. > > -With a `-m` or `-M` option, <oldbranch> will be renamed to <newbranch>. > -If <oldbranch> had a corresponding reflog, it is renamed to match > -<newbranch>, and a reflog entry is created to remember the branch > -renaming.

But the halfway modification to the description section in this patch is not an improvement. It makes some options described there while -m and -c are completely missing now, making the section incomplete and coverage of the operating modes of the command uneven. > +-m [<oldbranch>] <newbranch>:: > +--move [<oldbranch>] <newbranch>:: > + Rename an existing branch `<oldbranch>` to `<newbranch>`; if left > + unspecified, `<oldbranch>` defaults to the current branch.

OK. This is way more readable than the previous attempts we made. The description of the single failure mode still worries me (see my previous message on this). Here is my attempt: When the command fails due to an existing '<newbranch>', you can use `-M` (or `--move --force`) to force overwriting it. to hint that there may be other ways for the command to fail, and hint that `-M` may not always resolve issues, but I do not know how successful it is. I could add Note that `-M <old> <new>` will not resolve an error if the reason why `-m` fails is to protect the other worktree that checks out (or otherwise uses) <old> and <new> points at a different commit. but we do not necessarily want to appear to be exhaustive here, so, I dunno. > +-M [<oldbranch>] <newbranch>:: > Shortcut for `--move --force`.

Exactly the same comment on "other failure modes" applies here. > -<oldbranch>:: > - The name of an existing branch.
