Message:

cursor location improved; other behavior
The cursor locater now handles wrapped lines /better/ but still messes up
 when the line is the width of the screen and the cursor is at the end
 (so it should be a the beginning of a blank screen line)
C-a set the goal column
kill-to-end-of-line will eat a final newline and thus join.
