Massive detabbing of the source

[Jan Stolarek]

I thought I could clean up the source code from all the tabs and then remove {-# 
OPTIONS -fno-warn-tabs #-} pragmas + comment below it. This is a massive change though (140 files 
would be affected) and I suspect it could potentially be a problem to others working on the 
source (could cause some merge problems). So, can I just proceed with cleaning up all those 140 
files and then send a single patch or should I devide this task into smaller ones (e.g. a single 
patch for every directory in the $(TOP)/compiler/) or should I just give up on this idea?
