shuoldUpdateRoute -> shouldUpdateRoute 😀

when will you merge this pr?

@LinusBorg @posva hello, when will this pr be merged?
or is there some reason that this pr won't be merged?

I will use this feature soon.

I still have to properly test this. It's a bit weird to never use the fallback option in the check

@posva
in src/index.js line 45

this.fallback = mode === 'history' && !supportsPushState && options.fallback !== false
if (this.fallback) {
    mode = 'hash'
}

we know when we are in history mode(src/history/html5.js) and we are in a browser that doesn't support push state, then we know we have set the fallback option to false manully. if not, we will use src/history/hash.js .

so we don't need to check the fallback option, just need to check if we are in history mode and we are in a browser that doesn't support push state.

the logical is: when we are in history mode, and the browser doesn't support push state, and the router has already initialized. we should just jump(window.location[replace ? 'replace' : 'assign'](url)).

thank you.

ps: I have tested this on my ie9 and it works well.

@posva @LinusBorg hello, is this ok? should I do something? /(ㄒoㄒ)/~~
