not sure, if importing readline really gets the desired result (if I
understand the initial question correctly)
suppose the following input:
> this is ym first line
> and another line
(oops there's a typo in the first line, user hits cursor up two
times, and corrects it)
> this is my first line
what the program will then reads is:
"this is ym first line"
"and another line"
"this is my first line"
with no chance to see that the third line is supposed to replace line one.
Or is readline actually more powerful than I remember?
