A tiny improvement, substituting $/ for "\n":

perl -e '$b-=$a=1;for(A..T){$c=$a;print$a+=$b,$/;$b=$c}'

s**lil*; $*=join'',sort split q**; s;.*;grr; &&s+(.(.)).+$2$1+; $; = qq-$_-;s,.*,ahc,;$,.=chop for split q,,,reverse;print for($,,$;,$*,$/)

    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,$/for A..J'
      perl -le'print$a+=$b,$/,$b+=$a||1for A..J'
