+ * Simplified version of the prefork/singsub processing where
+ * we only do substitutions appropriate to quoting. Currently
+ * this means only the expansions in $'....'. This is used
+ * for the end tag for here documents. As we are not doing
+ * `...` expansions, we just use those for quoting. However,
+ * they stay in the text. This is weird, but that's not
+ * my fault.
+ *
+ * The remnulargs() makes this consistent with the other forms
+ * of substitution, indicating that quotes have been fully
