+- .if n .ce in the middle of .TS data

+ 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.
