New description:
Using Sage, you are missing a feature of the Magma command line interface.
In Magma, if you enter a line found in history using up arrow key and then
press down arrow key, then the next line in history is fetched. This
feature allows you to fetch as many successive lines in history as you
like. However, Sage does not have a similar feature. The IPython command
prompt uses the readline library (via pyreadline), which evidently does
not support this feature. Magma has its own custom “readline-like”
library, which does support this feature. (Since so many people have
requested this feature, if anybody can figure out how to implement it,
then such an implementation would certainly be welcome!)
This ticket addresses the above implementation.
