`de` fails at the end of the file

[jacekkopecky]

when the last line is not empty and the cursor is on the last character, de will not do anything where it should delete the last character; I may look at this because it's probably related to #555 and #581.
Also because of the same bug, ce at the last character of the non-empty last line behaves like i but should behave like s.
