+/**
+ * Scans between two parens and adds additional parens if needed.
+ * This function is recursive. If it hits another open paren, it'll call itself
+ * with the new bounds.
+ *
+ * Adds optional parens in an IF or SWITCH conditional statement.
+ *
+ * This basically just checks for a CT_COMPARE that isn't surrounded by parens.
+ * The edges for the compare are the open, close and any CT_BOOL tokens.
+ *
+ * This only handles VERY simple patterns:
+ * (!a && b) => (!a && b) -- no change
+ * (a && b == 1) => (a && (b == 1))
+ * (a == 1 || b > 2) => ((a == 1) || (b > 2))
+ *
+ * FIXME: we really should bail if we transition between a preprocessor and
+ * a non-preprocessor
