'frame', 'stepi'. The python frame filtering also respect this setting.
The 'backtrace' '-frame-info' option can override this global setting.

+ Enable the "compact" display mode for the TUI source window. The
+ compact display uses only as much space as is needed for the line

+Set whether the TUI source window is displayed in ``compact'' form.
