         Fix type used in example code
         man complex (from release 3.18) contains the following code:
-            complex z = cexp(I * pi); 
-        Reading the C99 standard, "complex" is not a valid type, 
+            complex z = cexp(I * pi);
+        Reading the C99 standard, "complex" is not a valid type,
         and several compilers (Intel ICC, ARM RVCT) will refuse to compile.
         It should be
             double complex z = cexp(I * pi); instead.
