+  While roff_parseln() prevents .ce and similar requests in the middle
+  of a tbl, the guard is no longer effective when the .ce is wrapped
+  in a roff block, for example a conditional.  The resulting assertion
+  has never been seen in any real-world manual page.
+  This is too dangerous to fix before release because it requires
+  reorganizing the very delicate internals of roff_parseln(),
+  which risks causing more severe bugs.
