- I traced this to an incorrect interpretation of the TAB character.
- TAB was being used by emacs (and vi) to optimize cursor motion. A
- VT100 TAB only moves the cursor, but TE/2 incorrectly blanks the
- characters which the TAB moves across. I was told that a later
- version of COMMPAK.DLL corrects this, but I fixed it by telling unix
- "stty tab3", which says "my terminal doesn't support hardware tabs and
- could they be expanded to spaces, please?"
