[[
If the character is the second character and is "-" (U+002D) and the first character is "-" as well, then the escaped character.
]]

css-syntax changed to allow --foo so maybe CSS.escape() shouldn't escape it?

Polyfill + tests updated: https://github.com/mathiasbynens/CSS.escape/commit/3ff1913c7ac411a9108ef528aceb3cb6c1e0918d
Comment 3 Mathias Bynens 2015-09-07 18:08:10 UTC 
This is problematic in browsers that ship `CSS.escape` before shipping an updated CSS parser (as per the latest css-syntax): https://code.google.com/p/chromium/issues/detail?id=528972#c3
Comment 4 Simon Pieters 2015-09-08 04:35:49 UTC 
- and -- are not identifiers. Blink implements css-syntax. This is a bug in CSSOM.

Oops, misread css-syntax. '--' was OK.
