I've done the same thing just last week.  I've started to collect them into a 
module called stringtools, but I see no reason why they can't reside in the 
string module.

I think this may be just a case of collecting these type of routines together in 
one place so they can be reused easily because they already are scattered around 
pythons library in some form or another.

Another tool I found tucked away within a pydoc is the console pager that is 
used in pydoc.  I think it could easily be a separate module it self.  And it 
benefits from the line-based abstraction as well.
