I've tried to address this in small steps, and checked in a new builtin,
PRECIOUS, that prevents removal of a target when update fails.
See:

        https://svn.boost.org/trac/boost/changeset/60157

Does this help at least half-way? If it mostly works, I'll implement an indirection
to decide if to retain target based on exit code.
