An option of type OPTION_SET_INT can be defined to set its variable to
zero. It's negated variant will do the same, though, which is
confusing. Several such options were fixed by disabling negation,
changing the value to set or using a different option type:
991c552916 (ls-tree: fix --no-full-name, 2023-07-18)
e12cb98e1e (branch: reject "--no-all" and "--no-remotes" early, 2023-07-18)
68cbb20e73 (show-branch: reject --[no-](topo|date)-order, 2023-07-19)
3821eb6c3d (reset: reject --no-(mixed|soft|hard|merge|keep) option, 2023-07-19)
36f76d2a25 (pack-objects: fix --no-quiet, 2023-07-21)
3a5f308741 (pack-objects: fix --no-keep-true-parents, 2023-07-21)
c95ae3ff9c (describe: fix --no-exact-match, 2023-07-21)
d089a06421 (bundle: use OPT_PASSTHRU_ARGV, 2023-07-29)
Check for such options that allow negation in parse_options_check() and
report them to find future cases quicker.
