Well, it turns out you actually can. We don't have Guido's time machine, 
but still there is a configuration option in Tk, albeit a very obscure 
one: you have to set the global Tcl variables tcl_wordchars and 
tcl_nonwordchars after loading Tk to a regexp which defines the word 
boundaries:

Strangely, there is a different preset for Windows and X11. The Windows 
preset - consider everything besides space as part of the word - makes 
more sense to me than the Unix default, which only counts letters, 
numbers and underscores as part of the word. To set the Windows preset, 
do this:

tk.eval('set tcl_wordchars {\S}');
tk.eval('set tcl_nonwordchars {\s}');

(untested in Python, only tested directly from a wish shell)
