At least Andrew seems to prefer cleaning up in the same patch. Anyway, I 
don't think Jeff meant that you shouldn't do any cleanups, but that you 
should try to respect the existing style as much possible. There are 
things that are almost generally agreed upon, such as removal of redundant 
typecasts, redundant wrappers, and moving assignment out of if statement 
expression. Formatting and the dreaded sizeof thing, however, 
are not, so it is best to keep them as-is.
