You could try using tags. Tag the characters on the last line, and then
using tag_configure(), change the spacing3 attribute.
Here is my quick hack that almost works. The problem seems to be that
the definition of 'end' changes depending on whether there is a single
newline at the end or not. But it may be a start.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
import Tkinter
if __name__ == '__main__':
root = Tkinter.Tk()
t = Tkinter.Text(root)
t.pack()
# Initialize with text
t.insert( 'end', "abc\n" * 50)
t.yview_moveto(1.0)
# Setup tag of last line and increase spacing underneath
t.tag_add('mylast', 'end - 1 lines', 'end - 0 lines')
t.tag_configure('mylast', spacing3="30")
root.mainloop()
