[Tutor] curses.textpad.Textbox.gather()

[Alex Kleider]

"""
I expect this will be of interest only to those using the curses
module.

I found that the Textbox.gather method seems incapable of returning
a string without a trailing space. The problem is easily solved by
using str.strip() as in the last line of my function (provided below)
but I'm wondering if there's a better way. Specifically to provide the
user with the option of having or not having a trailing space.
