I want to think about this one a bit more.  The ppc_md.progress()
calls aren't only used for the i/pSeries op panels, and I need to
think about the effect of \f on the other progress implementations.
It would be best, I think, if the outputting of \f could be done by
the pSeries progress function rather than the caller, if possible.
