The sample implementation of SRFI 146 includes code for a SRFI 128
implementation.  That bundled version of the SRFI 128 code is
out of sync with the main implementation for that SRFI and, most
important, has a very insidious bug in the default comparator.

Going over the SRFI 128 mailing list archives, I found that the bug was
fixed by Will Clinger in May 2016, but that fixed version does not seem
to have made it over to the SRFI 146 code.

I think one fix is pretty simple; just syncing up the SRFI 128 files
should do it.  However, perhaps a better fix is to unbundle the SRFI 128
implementation from the SRFI 146 code in order to avoid similar issues
down the road.
