You're probably going to be better off using ${PREFIX:a} rather than
cd.  I also wonder if it would be better only to look at previous
directory components, i.e. always take the PREFIX up to the last "/"
(and require that there be one) rather than have two cases.

I doubt there's much you can do better if you're completing in the
middle of the word.   If COMPLETEINWORD is not set, so you're sensitive
to $SUFFIX, you might use $PREFIX$SUFFIX, but apart from that $PREFIX
looks like the only interesting bit for path resolution.  This is rather
specialised.
