The changes look good!

There is also the case of adjacent tokens, where the same should be done:

eslint/lib/rules/one-var.js

Lines 321 to 323 in e460346

	if (afterComma.range[0] === tokenAfterDeclarator.range[1]) {
	return fixer.replaceText(tokenAfterDeclarator, `; ${declaration.kind} `);
	}

/* eslint one-var: ["error", "never"] */

export const foo = 1,bar = 2;
