 The 'atom' is the major blob in math typesetting.  And 'atom' consists
 of a nucleus, an optional superscript, and an optional subscript.
 
 Exactly where the subscript and superscript are drawn depends on the
-size, and type, of the nucleus they are attached to.  
+size, and type, of the nucleus they are attached to.

 hackish. We use MathAtom only as a wrapper around MathInset * with value
 semantics.
