Ulrich,

Yes: I should fix this.  And it's done.  This flushed out another bug
such that statements closing a conditional, e.g.,

  hello \} there

should be passed verbatim to the front-ends (if allowed by the
conditional), which would ignore the \}.  This has also been fixed,
hence the added escape in chars.{c,in} and mandoc.c update.  A
regression test has been added to this effect.

Thanks!

Kristaps
