- * Marker used in paramsubst for rc_expand_param.

+ * Marker is used in the following special circumstances:

+ * - In pattern character arrays as guaranteed not to mark a character in
+ *   a string.
+ * - In assignments with the ASSPM_KEY_VALUE flag set in order to

+ *   comes from [key]=value the Marker is followed by a null;
+ *   if from [key]+=value the Marker is followed by a '+' then a null.
+ * All the above are local uses --- any case where the Marker has
+ * escaped beyond the context in question is an error.
