A zero change delta consists of a "single copy" command. This command 
includes a length, so you will get different "zero delta" files for 
different length files. You also get a "single copy" command for a file 
that has been truncated, so it's not that trivial to check if the single 
copy command is really a "zero delta" or a truncation.

There are other tools that are better for detecting "zero-changes" than 
rdiff... it's something it could do but currently doesn't...
