$ emacs -Q -nw
abc123
C-h l
shows:
ESC [ > ESC [ > 4 1 ; 3 6 2 ; 0 c ESC ] 1 1 ; r g b : 0 0 0 0 / 0 0 0 0 / 0 0
0 0 ESC \ a ;; self-insert-command
b ;; self-insert-command
c ;; self-insert-command
1 ;; self-insert-command
2 ;; self-insert-command
3 ;; self-insert-command
C-h l ;; view-lossage
Notice the super-barfy first line?
The defendant swears he did not type that.
All he typed was the "a".
So please keep your termcap junk to yourself and don't pollute the C-h l
output.

Yeah, but as you see, you are "not in control of your bladder."
If you were, then the first line wouldn't shove the the innocent user's
"a ;; self-insert-command"
all the way to the right.
