Summary: a result of a differential equation is wrong

Initial Comment:
the solution of the differential equation 
(1+x)*'diff(y,x)+y=1+log(1+x); is %C/(1+x)+log(1+x). 
The command ode2(%,y,x)returns the following solution 
: y=((x+1)log(x+1)+%C-1)/(x+1). It looks like there's 
an error of sign (with the -1 which multiplicate the 
constant %C)
