The original motivation was to prevent problems with backup systems,
which make backups of any modified files. A few routines (coreg &
realign) only adjust the information in the headers. At the time, I
figured that it may not be a good idea to back up all the image data
just because of a small change to the headers. Apparently it's not an
issue though.
Maybe we'll go through the 400,000 lines of MATLAB code and change the
way things are done for the next SPM release.
All the best,
