(a) Allow an empty sender to be matched against a lookup in an address list.

Previously the only cases considered were a regular expression, or an
empty pattern.

(b) Fixed typo in the FAQ ("prefix" should have been "local_part_prefix").

 28. Installed the latest version of exipick from John Jetmore.
 
+29. In an address list, if the pattern was not a regular expression, an empty
+    subject address (from a bounce message) matched only if the pattern was an
+    empty string. Non-empty patterns were not even tested. This was the wrong
+    because it is perfectly reasonable to use an empty address as part of a
+    database query. An empty address is now tested by patterns that are
+    lookups. However, all the other forms of pattern expect the subject to
+    contain a local part and a domain, and therefore, for them, an empty
+    address still always fails if the pattern is not itself empty.
