Possible error in helper relative_url.js

[ghost23]

Hi,

i was having an issue with the generation of relative links in my paginations. I think, this line:

https://github.com/hexojs/hexo/blob/master/lib/plugins/helper/relative_url.js#L23

is wrong, it says:

if (outLength > 1 && !out[outLength - 1] && !out[outLength] - 2){

I think it should be (at the end, outLength -2):

if (outLength > 1 && !out[outLength - 1] && !out[outLength - 2]){

If I change that, my pagination works correctly.

Looks like this is fixed in master but hasn't been published for a release version yet (current 3.1.1)
