Deprecated selector in `blessed-light-syntax/index.less`

[nemoDreamer]

In blessed-light-syntax/index.less:

Starting from Atom v1.13.0, the contents of atom-text-editor elements are no longer encapsulated within a shadow DOM boundary. This means you should stop using :host and ::shadow pseudo-selectors, and prepend all your syntax selectors with syntax--. To prevent breakage with existing style sheets, Atom will automatically upgrade the following selectors:

atom-text-editor, :host => atom-text-editor,atom-text-editor
atom-text-editor .line.cursor-line, :host .line.cursor-line => atom-text-editor .line.cursor-line,atom-text-editor .line.cursor-line
