Breadcrumb variable interpolation breaking sourcemaps

[JoshMoreno]

For reference - #919

I think the above issue has to be reopened. Sorry if I should be posting there, kinda new to github and its issue/bug tracking.

So from what I can tell, there used to be an issue with how libsass compiled the following:

content: "#{$breadcrumb-separator}\00a0";

So it got changed to:

$nbsp: "\00a0";
content: "#{$breadcrumb-separator}#{$nbsp}";

But now that leads to it getting compiled to:

content: "/ ";

And on top of that if the libsass output style is set to compressed it causes source maps to be inaccurate. The other output styles are fine though. I submitted an issue over there - sass/libsass#2319

Proposition

Because this whole variable interpolation stuff is pretty unreliable and inconsistent across recent versions of libsass, I propose to just hardcode the value. So...

content: "/\00a0";

That way it will work for people using slightly older versions of libsass and also for people using the recent version(s). And though we won't have a simple variable to change/override, it's super easy to override the old fashion way. For example

.breadcrumb>li+li:before {
    content: "\003e\00a0"; // for a ">" instead of a "/"
}

I'd much rather have minified css and source maps than a variable for breadcrumbs. I know, as a work around, I could use a separate css minifier, but they add nearly one second to compile time. Libsass is fast and hard to beat and I really like to keep things simple and fast whenever possible.

Thoughts on this?
