Add `__fish_can_complete_switches` & `__fish_should_complete_switches` To be used by completions to directly determine whether it is either possible or preferable to complete a switch (instead of a subcommand), (presuming that switches must come before subcommands). * __fish_can_complete_switches: we are in a position where a switch may be placed. * __fish_should_complete_switches: we're in a position to accept a switch and the current token starts with `-` so we have no choice but to do so. 2018-04-20 06:52:20 +08:00			`# Returns whether it is at all possible (even if not recommended)`
