-So far we have carefully skirted around a potential
-problem; maybe you've wondered about it.
-Suppose we want to produce an equation that looks
-like this:
-.EQ
-x sup { pi + 1 }
-.EN
-The superscript is complicated, in that it contains
-both a $pi$ and a +1, which has to be separated
-from the $pi$ by a blank.
-But I already told you that a blank terminates
-the superscript.  What's going on?
-
-As the first step to finding out, will the input
-equation
-
-  x sup pi + 1
-
-produce the output
-
-  $x sup {pi + 1}$ ?
-Answer yes or no.
-(You can play with the file "Example" if you like.)
