Because errors don't have an unequivocal signature, nor do they have a defined
length. Also, if I say

    fit f(x) 'foo.dat' u 1:2 via a, b
    plot f(x), 'foo.dat' u 1:3
    print "OK"

the fit command will produce a lot of lines, and the plot command can still very
will fail, so there is absolutely no telling how long the output is. I really
don't see how one could determine how long one has to read.
