(1) fix macro invocation of _GDBN__ that didn't expand due to adjacent 's';

(2) attempt better text for when register relativization makes no diff.

-Register values are relative to the selected stack frame
+Normally, register values are relative to the selected stack frame
 (@pxref{Selection}).  This means that you get the value that the register
 would contain if all stack frames farther in were exited and their saved
 registers restored.  In order to see the contents of hardware registers,
 you must select the innermost frame (with @samp{frame 0}).
 
-Some registers are never saved (typically those numbered zero or one)

+However, _GDBN__ must deduce where registers are saved, from the machine
