Syntax Error for url(//...)

[donaldpipowitch]

The following code throws an error with 2.0.0-b1:

@font-face {
  font-family: 'Source Sans Pro';
  font-style: normal;
  font-weight: 200;
  src: local('Source Sans Pro ExtraLight'), local('SourceSansPro-ExtraLight'), url(//themes.googleusercontent.com/static/fonts/sourcesanspro/v5/toadOcfmlt9b38dHJxOBGLhZfOo4eSOlrve6pGrXHAo.woff) format('woff');
}

@font-face {
  font-family: 'Source Sans Pro';
  font-style: normal;
  font-weight: 300;
  src: local('Source Sans Pro Light'), local('SourceSansPro-Light'), url(//themes.googleusercontent.com/static/fonts/sourcesanspro/v5/toadOcfmlt9b38dHJxOBGIPZSf8Ud0kNoe3bGnF7K24.woff) format('woff');
}

SyntaxError: expected ')' got ''' in .../test.less on line 9, column 16:
8 @font-face {
9   font-family: 'Source Sans Pro';
10   font-style: normal;

Works in older Less versions.

Confirmed, the minimal example is:

x {
    y: url(//z);
}

It seems that now it interpreters // there as a comment.
(I guess this is because autoCommentAbsorb no longer has any effect at this point, no idea of how to fix it though).

[lukeapage]

we need to set autoAbsorb comment before calling the regex that will absorb url(
then undo it if it comes back with no match

[lukeapage]

I'll have a go at this now if you aren't doing it...

@lukeapage, yes, please :)
