AFAIK, they are talking about changing the amount of disk space that it takes 
up.  That would depend on the granularity of the fs, what is the smallest 
block that the fs can allocate.  As long as you do not change the number of 
blocks that the file uses, writing it back is no problem.  If you change the 
blocks used, then you need to worry about the directory entry and file tags 
and all that meta junk that is still experimental.
