Where do you see 2 extra 7s? In the input file (src/test/in/nfields), I have

p2=x^5+3021*x^4-786303*x^3-6826636057*x^2-546603588746*x+3853890514072057

hence the input

? p2=x^5+3021*x^4-786303*x^3-6826636057*x^2-546603588746*x+385389051407205
7 \\ 75th char wrapped

is correct. Or am I missing something?

On the other hand, now I see something "wrong": the next line has been
wrapped 4 characters too soon. This is due to the fact that "% = " (length 4)
used to be input in front of the result... and has been removed in this
last version (2.0.11, Changed 8). It's corrected in 2.0.12 (I don't think
anybody needs a patch for this?).
