It is perfectly acceptable to replace |jse?| with |js|jse| ... I don't believe there's any appreciable performance difference either way, and it's certainly more readable...
Though, perhaps, not as readable as

@bad_exts =
	"(" . join("|",
		qw/
ade adp app asd asf asx bas bat cmd com cpl crt dll exe

		/,
		"\\{[^\\}]+\\}"
	) . ")";
