I'm not sure this is a bug.  The man writer puts the whole "term" part of a 
definition list item in boldface.  This is the same default behavior you have 
in HTML and LaTeX definition lists.  I could change the default, but I don't 
see that the default is "wrong," and people may be relying on it...

In recent pandoc versions (1.6), the `blah` part is put in a non-proportional 
font, not boldface:

.TP
.B \f[C]blah\f[](1) blubb
err
.RS

I agree. However, it's still a bit annoying that there is no way to force parts 
of the "term" to non-bold. Don't know if there's a good way to do this without 
changing the default.
