Display feature request: gud-overlay-arrow

[Nick Roberts]

GUD currently points to the current line of the "selected frame" with the
gud-overlay-arrow.  This might be the innermost frame, where execution stops
which is called the "current frame", or it might be on higher in the stack
for example after the GDB command "up" or "frame N" where N > 0.

I would like to distinguish between the current frame and any other frame
by making keeping the gud-overlay-arrow solid when the selected frame is
the current frame and making it hollow (or different in some other way)
otherwise i.e make its appearance depend on a variable's value.

Is this possible?  Could it be a TODO item for the next release?
