Regardless of MI, the CLI is going to evolve.  This is because the 
current implementation is limiting GDB's functionality.

A few simple examples:

- signal backtraces.  They currently look something like:
	0x1234 in foo
	<signal handler called>
	0x456 in bar
but are about to be changed to:
	0x1234 in foo
	0x785 in <signal trampoline>
	0x456 in bar
This comes hand-in-hand with the raised expectation that operations such 
as "stepi"ing through a trampoline work (previously it was luck, 
typically bad :-).  For the user this is all good, but I bet there's a 
CLI parsing gui out there that breaks - oops.

- N:M breakpoints
Again, the user will easily adapt.
