[css-counter-styles-3] Invalid initial of negative, prefix, suffix

[cdoublev]

In the context of automatic parsing of a CSS value against a value definition, the initial field of the negative descriptor should be defined with a value that can be parsed against the value field. But the initial field is defined with "\2D" ("-" hyphen-minus).

I suggest using "\2D" or just "-" (I believe tokenization will replace \\2d by -) and to define in prose that it corresponds to ("-" hyphen-minus), or to use some kind of markup (containing ("-" hyphen-minus)) that provides additional details that w3c/reffy can read to separate it from the initial value.

FYI, @tidoust.

EDIT: the same issue applies to prefix, defined with "" (the empty string), and suffix, defined with "\2E\20" ("." full stop followed by a space).

Done. This is editorial so no WG confirmation needed. I also just switched to writing them with the actual characters rather than the escapes, they're all ASCII so I'm not sure why I was being weird about it.

Assuming commenter satisfied, since I did exactly what was asked. ^_^
