Thanks!
That's the best we can do with the sort-month test case
for now.

Currently, we have `ulimit -v` tests for cp, csplit, cut, dd, head,
printf, split and rm.  It seems an adaptive approach would work for
all of these programs - in regard to all of the
  --enable-single-binary={no,symlinks,shebangs}
cases.

The attached follows this approach - does it work for you?

Have a nice day,
Berny
