JAPH(just another perl approach),hehe:
perl -e 'map{chomp;$a[$i<3?$i:($i=0)].=$_;$i++}<>;print"@a\n";' filea +fileb filec
assumption that each file has the same number of lines, here line=3 for ease

[Corion]: ... foo "\0\0\0\n" bar\n by matching the first \n instead of matching the four-bytes-in- double-quotes part
[Corion]: ... and I still don't understand why ;)
