[css-nesting-1] Fix character reference errors

[andruud]

For example:
LINE 330:39: Character reference '&Bar' didn't end in ;.

Replaced various instances of & with &.

That's an obvious bugfix. So fine for me.

I'd argue that the enclosing in '' seems also wrong to me, because Bikeshed then tries to link those terms, but that can be done in a follow up.

I'd argue that the enclosing in '' seems also wrong to me, because Bikeshed then tries to link those terms, but that can be done in a follow up.

Note that the ''foo'' syntax has traditionally been used both for linking CSS values and for just marking stuff up in a particular style as CSS content. Bikeshed's cool with that. When it's occasionally problematic, the <css>...</css> fake element can be used for styling.

So continuing to use it for selectors as it is here is fine.

(This mixing is problematic in Bikeshed's parser impl - it needs to simultaneously parse as HTML and parse as raw text, and decide which is correct only after resolving links - but oh well.)
