14 Sept 2003 - Chris Watford watford@uiuc.edu
- Setup handler for up and down arrows
15 Sept 2003 - Chris Watford watford@uiuc.edu
- Setup framework for history on up arrow
- Saves lines you move off of in the edit buffer
16 Sept 2003 - Chris Watford watford@uiuc.edu
- Proper handling of newline message finished
- Fixed ENTER on middle of interior line, moves cursor to the end
and sends the line
- Setup the copying and destroying of the old buffer
- Included buffer rewrite
17 Sept 2003 - Chris Watford watford@uiuc.edu
- Added C-p/C-n support
- Changed UpArrow to C-UpArrow so as to not confuse users
18 Sept 2003 - Chris Watford watford@uiuc.edu
- Added Left and Right arrow line saving
- Added backspace and delete line saving and removing
- Fixed history scrolling
21 Sept 2003 - Chris Watford watford@uiuc.edu
- Fixed pasting errors associated with lines being out of bounds
for the buffer
- Added error handling, possibly able to handle it diff down the
line
- Removed C-Up/C-Dn for history scrolling, buggy at best on my
machine
