Really??  It would be a surprise to me that monotone's delta algorithm
would only be efficient for text files, because I have been using
monotone for many years on images and pdf files without problem
regarding performance.

I thought monotone uses xdelta, which is a binary delta algorithm that
facilitates binary merges that can be easily applied to both text and
non-text files.

Am I right, or is monotone's delta algorithm only efficient for text files?
