[RFC] Change displayed line when execution direction is reversed

My personal opinion:
In general, the state of the program when gdb is stopped is the state
at the start of the displayed line (I concede that it gets more
complicated when "step"ping)
This change would make it so the state is the state at the end of the
displayed line.

I think that could be confusing? Perhaps could be mitigated by
printing a message explaining that in some way.

The problem with this is that the user doesn't see what will be executed if a step is taken, which makes the user experience quite annoying. How would the community feel if GDB printed the previous line, instead of current line, when the execution direction is reversed?
