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.
