Unless you are trying to fix something, make it more efficient there is no 
reason to touch the code just because it looks bad. Some one might have lots 
of work done on said function and just about to send their changes in. Then 
come to find out that all of the changes have to be scrapped and rewritten 
because some one reformatted the code.

And it also helps if you actually understand what that piece of code is 
doing. Some code is kept ugly just so one day it can be properly rewritten 
not just reformatted.
