1. ## Bug

I was trying to display standalone percent/modulus sign ... and got some weird :
$%$

Namely, % if input bare-bones produces some long blank comment.
Obviously, one should escape the sign and get $\%$, but previous usage of % (and perhaps others) serves only as a potential exploit ... so it should be patched up.

2. $$\%$$ gives $\%$.

Not a bug but a >>feature<<

4. Ah, yes! First rule of software engineering- if you can't fix it, feature it!

It's a feature of LaTeX but a bug in the LaTeX add in we use (% starts a comment which ends with the line in a LaTeX document, but seems to give multiple blank lines here).

6. These also behave ishly: \vdot, \ldot, \ddot (\cdot is OK, as are all plural \dots).
