### Small note about an occurrence in PGML's centering

Hello,

I decided to try out a problem using PGML, and I initially had a few problems that got resolved just as I got used to the different syntax, but I noticed something that's a little disconcerting. Here it is.

This code:
>>[________]{$ans1}[f([$b])-f([$a])] [_______]{$ans2}  <<

runs perfectly and gives me a nice centered inequality with answer blanks. However, upon editing this, I noticed that this code:

>>[________]{$ans1}[f([$b])-f([$a])] [_______]{$ans2}  <<

does not run perfectly. It gives me something that looks closer to this.
< f(b)f(a)<  <<
It's the equation that I wanted, but right justified and with "<<".
"What's the difference?" you're probably asking, and that's the problem. The only difference is a space after the "<<" in the second piece of code.
I imagine this is something that might be changeable. It might cause some other people some trouble, so I thought I'd point it out. (By the way, it works the same way on the other side. If "<<" has a space before it, it causes a similar phenomenon.)
