Subject: [PATCH v4 4/7] doc: git-checkout: clarify `-b` and `-B`
Date: Wed, 10 Sep 2025 19:14:26 +0000	[thread overview]
Message-ID: <e636475cba2246ea98e461579a25b41b0ef4e99d.1757531669.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1962.v4.git.1757531669.gitgitgadget@gmail.com>

From: Julia Evans <julia@jvns•ca>

From user feedback: several users reported having trouble understanding
the difference between `-b` and `-B` ("I think it's because my brain
expects it to contrast with `-b`, but instead it starts off explaining
how they're the same").

Also, in `-B`, 2 users can't tell what the branch is reset *to*.

Simplify the sentence structure in the explanations of `-b` and `-B` and
add a little extra information (what `<start-point>` is, what the branch
is reset to).

Splitting up `-b` and `-B` into separate items helps simplify the
sentence structure since there's less "In this case...".

Replace the long "the branch is not reset/created unless "git checkout"
is successful..." with just "will fail", since we should generally
assume that Git will fail operations in a clean way and not leave
operations half-finished, and that cases where it does not fail cleanly
are the exceptions that the documentation should flag.
