mdocml: When showing more than one formatted manual page, insert

[schwarze@mdocml.bsd.lv]

Log Message:
-----------
When showing more than one formatted manual page, insert horizontal lines
between pages.  Suggested by Theo Buehler <theo at math dot ethz dot ch>.
Even in UTF-8 output mode, do not use fancy line drawing characters such 
that you can easily use /^--- to skip to the next manual in your pager.
