IABot adds spacing to the |interviewer argument .. however this causes the template in the wikitext to look messed up. The original authors had the "=" lined up so it is easy to read and looks nice. The number of spaces between the end of the argument name and the "=" sign are variable. But the total number of characters (include spaces) from the start of the argument name to the "=" would be the same for all arguments.
I ran into this wiki Medic and came up with some functions to determine spacing and have the "=" signs lined up (assuming that was the original intent).
