Newer versions of pristine-tar have become a fair bit stricter. If
they're not able to figure out the compression method, they fall back
to storing the entire compressed file. There is now a cap on the size
of the delta that is stored - so that it won't generate a 500Mb delta
if it can't find out the compression options for a .xz file.
