nonRelative
function nonRelative(path: string): boolean;
nonRelative(value) is the same test as !isRelative(value), written so that a guard clause reads as a sentence rather than as a negation.
The exact complement of isAbsolute: anything that does not start at a root, which includes the empty string.
isX and nonX answer a question and never interrupt control flow; requireX and requireNonX hand the value back or throw. The scheme is explained in Validation conventions.
Parameters
