Ah, good point.

For bitfields with more than named fields, I think my changes are 
very helpful.  For completeness, you can of course use 
bitfield_string to represent named fields as well as more complicated 
bitfields.

And even if you're only doing named fields, these changes might be 
preferable.  They provide a convenience routine to generate the 
entire string of bits set (rather than doing it by hand).  And 
perhaps more importantly, they provided a routine to generate the 
subtree showing the bitfield detail (which I personally find helpful).
