I guess this was done because people prefer the General Purpose register to be
shown in hex, not in decimal (they are integers, so their natural format would
be decimal).  I vaguely remember the default being natural in some ancient times.

This will be fixed when "register groups" are in place, as they will give us
information about how things should be displayed.  It is not a good idea to 
put some weird hack in place when all the user has to do is to change the 
FP register formats to whatever they want.  The format will "stick" between
debugger sessions.  So I suggest you dismiss this one or make it an enhancement
request (this is not even close to a bug).

Are we running out of real bugs?  This looks good!
