The parseopt parsing for OPT__QUIET() is implemented in terms of
OPT_BOOLEAN aka OPT_COUNTUP, so a user _could_ theoretically have
used it to make "git cmd -q -q" and "git cmd -q" behave differently.
However, no existing user does so (a summary of the audit at the
end). Use OPT_BOOL to make sure our choices are either 0 or 1.
builtin/branch.c:
quiet is passed to create_branch() in branch.c and
delete_branches(). The former passes it to setup_tracking()
which is used as a bool to decide use of BRANCH_CONFIG_VERBOSE.
The latter uses it as a bool to give a single printf() for
reporting the names of deleted branches.
builtin/check-ignore.c:
all users of quiet use it as a bool.
builtin/checkout-index.c:
quiet is assigned to state.quite and only the latter is used
throughout the program. It is a single-bit bitfield.
builtin/checkout.c:
quiet is stored in checkout_opts.quiet which is of type int. It
is used in many places:
- reset_tree() uses it as a bool;
- merge_working_tree() uses it twice, as a bool at both
places;
- update_refs_for_switch() uses it three times, all as a bool.
It also passes it to create_branch() which we already verified
above.
- switch_branches() and switch_unborn_to_new_branch() use it
once each, as a bool at both places.
