Aha :)

Ah..

Just adding newline to make that happen seems to break the inline format 
macro. So..

a @precb{} b

Seems to do the trick, just /one/ little issue is that it doesn't seem to 
allow you to format the whole thing as math in one go, e.g.:

  @math{a @precb{} b}

Makes stuff unhappy.

Is there a way to make that work?

Thanks very much! :)
