Merge branch 'ph/diffopts'
* ph/diffopts: Reorder diff_opt_parse options more logically per topics. Make the diff_options bitfields be an unsigned with explicit masks. Use OPT_BIT in builtin-pack-refs Use OPT_BIT in builtin-for-each-ref Use OPT_SET_INT and OPT_BIT in builtin-branch parse-options new features.
