Tkinter.Text can never be empty?

[Harry Pehkonen]

While setting up some unit tests, I came to the conclusion that a
Tkinter Text widget can never be empty, but will always (?) contain a
\n. Here is a brief example:

import Tkinter
t = Tkinter.Text()
t.get(0.0, Tkinter.END) '\n' t.delete(0.0, Tkinter.END)
t.get(0.0, Tkinter.END) '\n'

My apologies, but I have not checked whether or not this can be
reproduced in Tcl/Tk (which I think might have been appropriate).

My question is: Is there *always* a trailing \n, is this a bug, or am
I doing something silly?

Thanks!
Harry.

Nope, this is one of the idiosyncrasies of our friend the Text widget;
there's always this immortal LF at the end.
