The good part is that it is very easy to add xz support to xdelta,
just a one line patch :

Also we do not have the same problem than with gzip timestamps. the
md5sum of the patched file is identical without any tricks. I wonder
about bzip2.

In any cases, the sync.c code will needs to be patched, and maybe it
is possible to do it now by reworking the code a bit, to support both
the current and future situation.
