Hi,

As discussed on tech@openbsd.org,

http://comments.gmane.org/gmane.os.openbsd.tech/24663

we're missing two symbols defined in tmac.doc.  The enclosed patch 
includes them (not the documentation bits for mandoc_char.7, which I'd 
include if this is ok'd).

For the record, I don't particularly like these as they discourage using 
`St' in favour of hand-rolling standards.  I think this should be taken 
into account when deciding on whether to ok this.

So... thoughts?
