uploaded and ready for the SRU Teams review

** Description changed:

+ [Impact]
+ 
+  * Perl version in Artful complains about deprecated regex usage in 
+    spamassassin. This works but floods consoles and status mails.
+ 
+  * Fix is a backport of the small upstream change
+ 
+ [Test Case]
+ 
+  * simply run sa-learn in any way, for example
+      $ sa-learn --help
+    In unfixed versions you'll see the following all over the place (also 
+    on install and in status mails)
+ 
+      Unescaped left brace in regex is deprecated here (and will be fatal 
+      in Perl 5.30), passed through in regex; marked by <-- HERE in m/^(.{ 
+      <-- HERE ,200}).*$/ at 
+      /usr/share/perl5/Mail/SpamAssassin/PerMsgStatus.pm line 923.
+ 
+  * these should allow someone who is not familiar with the affected
+    package to reproduce the bug and verify that the updated package fixes
+    the problem.
+ 
+ [Regression Potential]
+ 
+  * sa-learn worked in some tests, but there could be unexpected 
+    cases where this breaks by very slight behavior changes.
+    OTOH the change is upstream a while now, so the chance it
+    really broke anything is low.
+    Also the change is essentially 1 chomp moved and 3 pattern matches 
+    adapted to new syntax - so the amount that slips our review thoughts 
+    should be low.
+ 
+ [Other Info]
+  
+  * n/a
+
