Subject: [PATCH] Markdown.pl: add bdo to taga1p

The "bdo" (Bi-Directional Override) container element always requires
at least one attribute to be present for it to be valid.  Specifically,
in this case, the "dir" attribute.

Add "bdo" to the `%taga1p` (TAGs requiring Attributes count of 1 Plus)
hash to reflect this.  A bare "<bdo>" will now be passed through to
the output as "&lt;bdo>" when using the default options.
