the changes to the prerequisite patch 1 in the series and
a couple of minor simplifications and slightly improved
test coverage, rested on x86_64-linux.

Hi Andrew,
Thanks for your detailed comment. There are two problem I wanted to discuss

optimization and a link for the proof i

My last change to the fully-dynamic-string actually broke it. This fixes
the move constructor so it builds, and simplifies it slightly so that
more code is common between the fully-dynamic enabled/disabled cases.
