A tiny improvement, substituting $/ for "\n": 
perl -e '$b-=$a=1;for(A..T){$c=$a;print$a+=$b,$/;$b=$c}'

    I can shave off a couple characters by leveraging the fact that the length of the sequence is even. Also, the OP's sequence starts with F1=1, so if I start there too I don't have to initialize both variables. 
    perl -e '$a=1;for(A..J){print$a+=$b,$/,$b+=$a,$/}'

    Update: Now that the loop is down to 1 statement I can switch to a postfix for. I can also fold the initialization into the loop. 
    perl -e 'print$a+=$b||1,$/,$b+=$a,$/for A..J'

    ... and if you feel strongly about starting with F0=0, 
    perl -e 'print$a+=$b,$/,$b+=$a||1,$/for A..J'
