+   The match{}{} expansion condition (for regular expressions) is NOT affected.
+   For match_<type>{s1}{s2}, all list functionality is unchanged.  The only
+   change is that a '$' appearing in s2 will not trigger expansion, but instead
+   will be treated as a literal $ sign; the effect is very similar to having
+   wrapped s2 with \N...\N.  If s2 contains a named list and the list definition
+   uses $expansions then those _will_ be processed as normal.  It is only the
+   point at which s2 is read where expansion is inhibited.
+
+   If you are trying to test if two email addresses are equal, use eqi{s1}{s2}.
+   If you are testing if the address in s1 occurs in the list of items given
+   in s2, either use the new inlisti{s1}{s2} condition (added in 4.77) or use
+   the pre-existing forany{s2}{eqi{$item}{s1}} condition.
