pygrub: Allow scrolling of the list of entries
|
|
|
|
When user wants to change entry in grub2 menu in pygrub, there
|
|
may be crash of pygrub in case of editing item ('e' key).
|
|
|
|
Crash on editing is caused longer entry list in case of grub2. As entry
|
|
window is 10 lines high, it can hold only 8 entries (2 lines for border).
|
|
Adding line outside of windows high causes crash. Patch add handling
|
|
for longer lists and scrolling through them.
