When you referenced a glossary item in the text of a post, it would appear to add a blank character after the reference. 

So you would end up with text that looked like this 1999.io .

Not good. I looked into why it was doing this and the fix was easy. It was actually adding two extra whitespace characters (CR and LF) after the text. 

Now you end up with no extra space: 1999.io.

It was easily fixed by not doing that. ;-)

The fix is in v0.90p.
