Multiline text field notice/typo

I believe that there is a typo in the text module which causes a notice and also causes some sort of filter related bug.

Steps to repeat:
1. Add a multi-line text field to a node
2. Visit the node/add page

Expect results:
No notices

Actual results:
notice: Undefined offset: 1 in /home/.beanor/knaddiso/d6/sites/all/modules/cck/modules/text/text.module on line 450.

Looking at that line, the condition passed to the if statement seemed weird to me. It does a count on an equality test (i.e. a count on a boolean) rather than comparing the count of an array to the number 2.

The attached patch fixes the notice and didn't seem to introduce any bugs.
