sloppy hackery diff against glr

Also... jerry-rig sprintf to work for most purposes

As far as I got with GLR.  With this at least most of the first exception
prints, then followed by a "Cannot assign to an immutable value" which happens
inside a mystery member of @END_PHASERS which I cannot track down,
and magically turns into a Seq-already-iterated if you print anything
inside the Deprecations END or after it in the THE_END loop.

There are actually only two test failures in 01-sanity.  "print 1"
and the "string COW" test which does not even wait to get to the
COW part before complaining about immutability.  Probably an
assignment/decont problem.

Adjust "is-win" below by hand as $*DISTRO is not working.
