I use Sass and when I run comb in Sublime Text 3 with the following example

input,
button,
select,
textarea
    font-size: inherit
    line-height: inherit

I always get an error on space-after-selector-delimiter.js. This doesn't occours when selectors are 2 or less, or inline like below

input, button, select, textarea
    font-size: inherit
    line-height: inherit
