Doh! You are right, I confused that with target names, where we have a 
restriction on what names are allowed. Brad, what about nuking at least all 
control characters and whitespace from variable names in 3.1? I don't think 
that anyone has used them on purpose, and accidentially using them will only 
cause trouble.
