Oh, wait. I just remembered why we don't do this already. Keyword
substitution/EOL translation. I think our full algorithm is:

   if timestamps not different:
       return no_diff
   if keywords or eol-style enabled:
       de-translate file to tmpfile
       if tmpfile size != basefile size:
           return diff
       if tmpfile and basefile differ bytewise:
          return diff
   if file size != basefile size:
       return diff
   if file and basefile differ bytewise:
       return diff
   return no_diff
