Re: [PATCH v2] switch: fix errors and comments related to -c and -C

> In d787d311db (checkout: split part of it to new command 'switch',
> 2019-03-29), the `git switch` command was created by extracting the
> common functionality of cmd_checkout() in checkout_main(). However, in
> b7b5fce270 (switch: better names for -b and -B, 2019-03-29), the branch
> creation and force creation options for 'switch' were changed to -c and
> -C, respectively. As a result of this, error messages and comments that
> previously referred to `-b` and `-B` became invalid for `git switch`.
>
> For error messages that refer to `-b` and `-B`, use a format string
> instead so that `-c` and `-C` can be printed when `git switch` is
> invoked.
