Deprecated selector in `proton-bat/index.less`

[DanayaMel]

In proton-bat/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:

• .variable.parameter.function => .syntax--variable.syntax--parameter.syntax--function

• .comment, .punctuation.definition.comment => .syntax--comment, .syntax--punctuation.syntax--definition.syntax--comment

• .punctuation.definition.string, .punctuation.definition.variable, .punctuation.definition.string, .punctuation.definition.parameters, .punctuation.definition.string, .punctuation.definition.array => .syntax--punctuation.syntax--definition.syntax--string, .syntax--punctuation.syntax--definition.syntax--variable, .syntax--punctuation.syntax--definition.syntax--string, .syntax--punctuation.syntax--definition.syntax--parameters, .syntax--punctuation.syntax--definition.syntax--string, .syntax--punctuation.syntax--definition.syntax--array

• .punctuation.definition.string => .syntax--punctuation.syntax--definition.syntax--string

Automatic translation of selectors will be removed in a few release cycles to minimize startup time. Please, make sure to upgrade the above selectors as soon as possible.
