I was uncertain about which flavor of ui_out to use also. From
Fernando's explanation and an off list comment I received from someone
else I learned that the really important information should be output
via ui_out_field_*. ui_out_text and it's derivative ui_out_spaces are
just for making the output "pretty" in the generic command line form of
GDB. GUI front ends to GDB typically write the output from
ui_out_field_* to a window but may completely ignore the output from
ui_out_text and ui_out_spaces.

This was not obvious to me when reviewing the implementation of the
UI_OUT functions.
