I just tested the following, it works as it should (with the -P):
        pref="${cur%\%*}"%
        suf="${cur##*%}"
        COMPREPLY=( $( compgen -P "${pref}" -W "abc bbb cde" -- "$suf" )

but I guess he would like the "other way"...
and I'm interested too in knowing how to deals with COMP_WORDBREAK,
(especially using properly the API)
