 The subtitution placeholders are like this:
 
     $1      # value is a string; the value is quoted and escaped
     $2:num  # value is a number; not quoted
-    $3:bool # value is a bool; "t" is true, "f" is false
+    $3:bool # value is a bool; "t" and "1" are true, "f" and "0" are false
 
 The placeholders start counting the first TSV value from position 1, not
 zero.
