Deprecated selector in `code-macro\index.less`

[JamesElliott9]

In code-macro\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 .wrap-guide, :host .wrap-guide => atom-text-editor .wrap-guide,atom-text-editor .wrap-guide

• atom-text-editor .indent-guide, :host .indent-guide => atom-text-editor .indent-guide,atom-text-editor .indent-guide

• atom-text-editor .invisible-character, :host .invisible-character => atom-text-editor .invisible-character,atom-text-editor .invisible-character

• atom-text-editor .gutter, :host .gutter => atom-text-editor .gutter,atom-text-editor .gutter

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

• atom-text-editor .gutter .line-number.cursor-line-no-selection, :host .gutter .line-number.cursor-line-no-selection => atom-text-editor .gutter .line-number.cursor-line-no-selection,atom-text-editor .gutter .line-number.cursor-line-no-selection

• atom-text-editor .gutter .line-number.folded, :host .gutter .line-number.folded, atom-text-editor .gutter .line-number:after, :host .gutter .line-number:after, atom-text-editor .fold-marker:after, :host .fold-marker:after => atom-text-editor .gutter .line-number.folded,atom-text-editor .gutter .line-number.folded, atom-text-editor .gutter .line-number:after,atom-text-editor .gutter .line-number:after, atom-text-editor .fold-marker:after,atom-text-editor .fold-marker:after

• atom-text-editor .invisible, :host .invisible => atom-text-editor .invisible,atom-text-editor .invisible
