=>+ as shortcut of partfrac

Hello BP.

1: Why two different answers?

autosimplify(2):;partfrac(1/(x^4-1)) returns
"Done",1/((x-1)*4)-1/((x+1)*4)-1/((x^2+1)*2)

autosimplify(2):;1/(x^4-1)=>+ returns
"Done",1/(x^4-1)


2: why 2D printing is different in the online version
https://www-fourier.ujf-grenoble.fr/~pa ... .html#sec4

autosimplify(2):;1/(x^4-1)=>+ returns

(1/4)/(x-1) - (1/4)/(x+1) - (1/2)/(x²-1) // online
versus
1/((x-1)*4)-1/((x+1)*4)-1/((x^2+1)*2) //xcas
