fix whitespaces,tabs coding style issue and ...

In my opinion this code was already correct, and would display correctly
at any TAB setting. This patch changes it so that it displays
incorrectly
at all TAB settings other than 8.

Example:

Correct:
<tabs>function(arg1,
<tabs><9spaces>arg2

Incorrect:
<tabs>function(arg1,
<tabs>< tab  > arg2

For any TAB setting other than 8, arg1 and arg2 no longer line up.
