[BUGS] initcap() whitespace bug

[Darrell Walisser]

It appears that "'" is being considered as a whitespace (and perhaps other 
punctuation, haven't checked myself):

initcap(text) " Convert first letter of each word (whitespace-separated) to 
upper case "

Sample SQL: select initcap('grahm''s little angel');
Incorrect Result (Note capital S): 'Grahm'S Little Angel'
Postgresql Version: 7.4.5
