some hashtags are not properly linked

In twitter_pull.module function twitter_pull_add_links($text) I replaced the hashtag pattern (the last one) with the following:

  $pattern = '/[#]+([\pL\pN]+)/u';

See http://ca.php.net/manual/en/regexp.reference.unicode.php for more info. Basically, a hashtag is comprised of unicode letters and numbers. That includes é, ç, etc. Not including dashes since they're not linked by Twitter.
