I've changed display commands as you suggested. I've also made 'break'
parts after 'enable', 'disable' and 'delete' optional as it is in gdb.

Well, to be clear, my intent was to allow displays to be bound to one
function: when you step out of it, or step into another function, the
'local' displays disappear, and when you happen to get back to the function
again - you have them intact. I think it works somewhat like that in DDD
for displaying local variables. In recursive calls you will see expressions
evaluated in currently selected stack frame ('up'/'down' should set
apropriate context for display/print/list/disassemble. Though I haven't
looked into it, yet.).
I s/frame/function/'d the display structure to be less confusing.
Second version appended.
