mandoc: Avoid artifacts in the most common case of closing conditional

[schwarze]

Log Message:
-----------
Avoid artifacts in the most common case of closing conditional blocks
when no arguments follow the closing brace, \}.
For example, the line "'br\}" contained in the pod2man(1) preamble 
would throw a bogus "escaped character not allowed in a name" error.
This issue was originally reported by Chris Bennett on ports@,
and afresh1@ noticed it came from the pod2man(1) preamble.
