-    Fix crash on #nil in syntaxes
-    
-    In 3.0.7 (after 0cc799185576712d69f11fc794454f2f5447bef7 "Ensure
-    that (syntax ()) results in ("), the use of #nil in syntax-rules
-    expansions like this:
-    
-      (define-syntax foo
-        (syntax-rules ()
-          ((_ x) (eq? #nil x))))
-    
-      (foo #t)
-    
-    could cause a crash that looks like this:
-    
-      ice-9/psyntax.scm:2795:12: In procedure syntax-violation:
-      Syntax error:
-      unknown location: unexpected syntax in form ()
-    
-    To fix it, add another special case (the commit mentioned above
-    special-cased the empty list) to preserve #nil
-    
-    * module/ice-9/psyntax.scm (gen-syntax): Preserve #nil.
-    * test-suite/tests/syntax.test: Test #nil in syntax expansions.
-    
-    Closes: 49305
