Actually, that's not true.  I did want to retain the timestamp 
preservation by default, but I wanted an option to be added that will NOT 
preserve the timestamp of a file that was changed.  Unchanged files 
should always have their timestamp preserved, even under the new option.

What I had in mind was simpler than what you implemented: I meant only 
two possible status values: 0 (no changes) and 1 (file changed).  
With that setup, I thought that in the case of several files, the exit 
status should be a logical OR of the statuses for all the files.  That 
is, if at least one of the files was changed, the exit status will be 1.

I didn't say that in my original message, but for compatibility reasons
(old Makefiles) it might be a good idea to return non-zero exit status
only under a special option, and retain the current behavior if that
option was not given. 

In any case, thanks a lot for working on this.
