Description

The formatter was wrongly adding space to some numbers. I've made a small "case" file, these are the results of the formatter:

-a = [.100000E+05]
-a = [.100000e+05]
+a = [.100000E + 05]
+a = [.100000e + 05]
 a = [.100000E05]
 a = [.100000e05]
 a = [0.100000E+05]
 a = [0.100000e+05]
 a = [0.100000E05]
 a = [0.100000e05]
 
-a = [.100000E-05]
-a = [.100000e-05]
+a = [.100000E - 05]
