wptexturize inserts prime mark instead of closing single quote

[paulschreiber]

In the following example:
The 'Big 6': Look here

WordPress inserts a prime mark:
The ‘Big 6′: Look here

Correct behaviour would be to insert a close quote:
The ‘Big 6’: Look here

Note that due to the font trac uses, you don't see a prime mark. You might need to do a view source to see the difference.
