Command menu in mcedit is too long for 80x25 terminal

[bilbo]

In mcedit, when I invoke the command menu while being in standard text mode (the 80x25 characters text mode that you get when you Xserver does not come up), the last line shown is "'ispell' spell check" - the rest four items are not visible. Since I often use mc to fix thing in text mode so X will start again, this could be fixed.

Either the menu could be shortened (there are 7 separators, removing at least four of them could do the trick), or the menu could be made scrollable, so large menus will be usable even on small terminals.
