Fix a panic when using 'dL' or 'dG'

TODO.md

 Known bugs:
 
 - [x] When using `t` with a char that isn't in the document, Sodium will crash.
-- [x] `d<motion>` does not do anything if: 1) the motion moves to the end of a line. 2) if the motion moves to the last line.
+- [x] `dG` on the last line of the file deletes from the cursor to the end of the line, instead of the entire line.
+      Not sure if intended.
 
 The bug causing these two bugs, is localised to be in position.rs. It resolves by returning a value one over bound x
