Conditional ensures that the present of First ensures the present of Second.

	// secondHasGroup records whether `Second` has a capture group. When it
	// does, a `First` match is allowed only if its value was captured by a
	// `Second` match (e.g. an acronym defined as `... (WHO)`). When it doesn't,
	// the rule is a plain presence check: any `First` requires `Second` to
	// appear somewhere in the same block. See #1048.

// hasCaptureGroup reports whether `pattern` contains a capturing group -- an
// unescaped `(` that doesn't begin a non-capturing/extension group `(?...)`.
