+
+# Explanation for this rule:
+#
+#    It needs to back over
+#        The $Sep at which we probably begin
+#        All of the non $Sep chars leading to the preceding $Sep
+#        The preceding $Sep, which will be the second one that the rule matches.
+#        Any immediately preceding STerm or ATerm sequences.  We need to see these
+#              to get the correct rule status when moving forwards again.
+#        
+# [{bof}]           inhibit rule chaining.  Without this, rule would loop on itself and match
+#                   the entire string.
+#
+# (.? | $LF $CR)    Match one $Sep instance.  Use .? rather than $Sep because position might be
+#                   at the beginning of the string at this point, and we don't want to fail.
+#                   Can only use {eof} once, and it is used later.
