Summary: string.title() doesn't understand apostrophes

Initial Comment:
Consider the following:

steveg@speedy:~/jbox$ python 
Python 2.2.3 (#1, Jun  4 2003, 02:54:59) 
[GCC 3.3 (Debian)] on linux2
Type "help", "copyright", "credits" or "license" for
more information.
>>> "I've fallen and i can't get up".title()
"I'Ve Fallen And I Can'T Get Up"
>>> 

That looks fairly non-standard to me. Apparently, the
title()
method treats apostrophes as whitespace/word
seperators/something.

Thanks,
Steve

Thanks, Raymond, for this investigation. 

Closing it as wont-fix - if you want an algorithm that
follows the English language rules, you have to implement
that yourself.

The determination of what actually constitutes a word is 
language-dependent.  For instance, in French, l'arbre is 
considered two words.  See:  
http://www.unicode.org/reports/tr21/tr21-5d3.html

Also, I tried the VB and MS-Excel implementations (they call 
it "proper" instead of "title") and they match the current 
Python behavior.  I found no equivalent string method in 
Java.

If the ' directly follows a letter, then it is being used for a 
contraction and not for indirect speech, and the following 
letter should not be uppercased.

Unfortunately, this usage of the apostrophe is specific to
the English language. Martin says, 'if the apostrophe is
used for indirect speech, upper-casing after it is correct'.
