The option callback for "apply --whitespace" exits with status "1" on
error. It makes more sense for it to just return an error to
parse-options. That code will exit, too, but it will use status "129"
that is customary for option errors.
The exit() dates back to aaf6c447aa (builtin/apply: make
parse_whitespace_option() return -1 instead of die()ing, 2016-08-08).
That commit gives no reason why we'd prefer the current exit status (it
looks like it was just bumping the "die" up a level in the callstack,
but did not go as far as it could have).

The options callback for --batch and --batch-check detects when the two
mutually incompatible options are used. But it simply returns an error
code to parse-options, meaning the program will quit without any kind of
message to the user.
Instead, let's use error() to print something and return -1. Note that
this flips the error return from 1 to -1, but negative values are more
idiomatic here (and parse-options treats them the same).

We do not allow "--no-message" to work now, as the option callback
returns "-1" when it sees a NULL arg. However, that will cause
parse-options to exit(129) without printing anything further, leaving
the user confused about what happened.
Instead, let's explicitly mark it as PARSE_OPT_NONEG, which will give a
useful error message (and print the usual -h output).
In theory this could be used to override an earlier "-m", but it's not
clear how it would interact with other message options (e.g., would it
also clear data read for "-F"?). Since it's already disabled and nobody
is asking for it, let's punt on that and just improve the error message.

Running "git show-branch --no-reflog" will behave as if "--reflog" was
given with no options, which makes no sense.
In theory this option might be used to cancel an earlier "--reflog"
option, but the semantics are not clear. Let's punt on it and just
disallow the broken option.

We have separate parse-options entries for "numbered" and "no-numbered",
which means that we accept "--no-no-numbered". It does not behave
sensibly, though (it ignores the "unset" flag and acts like
"--no-numbered").
We could fix that, but obviously this is silly and unintentional. Let's
just disallow it.

If you run "git status --no-find-renames", it will behave the same as
"--find-renames", because we ignore the "unset" parameter (we see a NULL
"arg", but since the score argument is optional, we just think that the
user did not provide a score).
We already have a separate "--no-renames" to disable renames, so there's
not much point in supporting "--no-find-renames". Let's just flag it as
an error.

Running "cat-file --no-batch" will behave as if "--batch" was given,
since the option callback does not handle the "unset" flag (likewise for
"--no-batch-check").
In theory this might be used to cancel an earlier --batch, but it's not
immediately obvious how that would interact with --batch-check. Let's
just disallow the negated form of both options.

Running "git pack-objects --no-index-version" will segfault, since the
callback is not prepared to handle the "unset" flag.
In theory this might be used to counteract an earlier "--index-version",
or override a pack.indexversion config setting. But the semantics aren't
immediately obvious, and it's unlikely anybody wants this. Let's just
disable the broken option for now.

Running "git ls-files --no-exclude" will currently segfault, as its
option callback does not handle the "unset" parameter.
In theory this could be used to clear the exclude list, but it is not
clear how that would interact with the other exclude options, nor is the
current code capable of clearing the list. Let's just disable the broken
option.
Note that --no-exclude-from will similarly segfault, but
--no-exclude-standard will not. It just silently does the wrong thing
(pretending as if --exclude-standard was specified).

The options callback for "git apply --no-include" is not ready to handle
the "unset" parameter, and as a result will segfault when it adds a NULL
argument to the include list (likewise for "--no-exclude").
In theory this might be used to clear the list, but since both
"--include" and "--exclude" add to the same list, it's not immediately
obvious what the semantics should be. Let's punt on that for now and
just disallow the broken options.
