For recursive diff, it would be useful to have an option to sort
the files in timestamp order to generate patches. I suspect that
users who apply patches do not always use the -Z patch option to
avoid time-dependency problems with "make". It seems that sorting
the files by time in a patch file would make the -Z option useless,
as I suggested here:

  https://sympa.inria.fr/sympa/arc/mpfr/2015-07/msg00006.html

Alternatively, this could be done by a separate utility (if this is
easier to implement, and to "correct" existing patches).
