[PATCH/RFC] Restructure some of the checkout opts.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Previously, most opts in `builtin.checkout.c' had been an instance of
`struct checkout_opts'. It appears that some of the opts that were
perhaps added later were not in the struct. Move them into the struct
in order to maintain consistency.
