This is a really cool problem! ++, MeowChow.

sub assemble {
$x='';sub a{($p,$q)=@_;return$q if!$p;$l=length$p;for(0..$l){$y=
substr($p,0,$_).$q;return$y if substr($y,0,$l)eq$p}}sub b{my$s;$s=a(
$s,$_)for@_;$x=$s if!$x||length$s<length$x;}
sub c{my($a,$b)=@_;if(@$b){for(0..$#$b){my@c=@$b;
c([@$a,splice@c,$_,1],[@c])}}else{b @$a}}c([],[@_]);$x
}

279 by my count. I know I could cut this down further in the recursion, but I'm damned if I can see it right now.
