-You may have noticed that neqn threw away the spaces
-in several of the examples we did. For example, in
-.EQ
-a = b + c - d
-.EN
-the output equation looks like
-a=b+c-d
-regardless of spaces in the input.
-
-Spaces are always thrown away, and so are new lines - you
-can type an equation on as many lines as you like.
-This latitude is permitted mainly to make it easy to type equations -
-longer equations are easier to edit when they are typed
-as a series of short input lines instead of one giant
-one.
-
-Will the printed output of this equation
-.EQ
-a
-+
-b
-+
-c
-.EN
-be any different from this one?
-.EQ
-a+b+c
-.EN
-Answer yes or no.
