[wp-hackers] Entity fix

[Kimmo Suominen]

I was trying to use ½ and ¾ in a post, and they kept
getting mangled by WordPress.  The patch below fixes the problem.

I'd add this to Trac, but it appears TextDrive (or theplanet.com)
is having network problems, so I can't even reach my own sites
hosted at TextDrive.

Regards,
+ Kimmo
