phases: apply similar early filtering to advanceboundary

advanceboundary is called the push's unbundle (but not the other unbundle) so

We start with simple pre-filtering to avoid doing any work if we don't needs
too.

# Disable the $CAP wire protocol capability.

if test -z "$CAP"
then
    echo "CAP environment variable not set."
