Block comments should be preserved in "static" at rules

When using @'s it appears to fail.

@-moz-keyframes animatetoptop /* Firefox */ line 429
{
from {width:0%}
to {width:100%}
}

I'll get the following error.

[16:36:40] gulp-notify: [Compile Error] stylesheets\apps\tmm\_results.scss
429:17  top-level directive must be terminated by ';'

I'm using gulp-sass: 2.0.1

I am unable to reproduce this specific error. However I have noticed we incorrectly remove the comment and adding maintaining the authors whitespace.

@-moz-keyframes animatetoptop /* Firefox */ line 429
{
from {width:0%}
to {width:100%}
}

Ruby Sass

@-moz-keyframes animatetoptop /* Firefox */ line 429 {
  from {
    width: 0%; }
  to {
    width: 100%; } }

Libsass

@-moz-keyframes animatetoptop line 429
{
  from {
    width: 0%; }
  to {
    width: 100%; } }

The adjancent string is parsed literally and the comment node is part of it. Related to At_Rule parsing (I already did some improvements for values). This sample shows the behavior:

@-moz-keyframes        animatetoptop       /* Firefox */         line 429   {
from {width:0%}
to {width:100%}
}

ruby sass:

@-moz-keyframes animatetoptop       /* Firefox */         line 429 {
  from {
    width: 0%; }
  to {
    width: 100%; } }

Related to #1263

Interesting you couldn't reproduce it. I wonder what it could be about my set up that would cause this if its not libsass. I will look into my other processes and see if its something else causing the problem.

thanks
