Regression in integration



I was looking at a message from Harry Christhian[1] about a bug in
integration, which I didn't quite understand, but I found the
following serious error:

(%i1) integrate(c/x^n,x);
Is n - 1 zero or nonzero?

nonzero;
(%o1)                              c log(x)

It doesn't matter whether you answer zero or nonzero; you get the
answer as if n = 1.

[1] Is it possible to directly send email to maxima-bugs?  Or should
only the bug tracker send email to that list?  Anyway, I think he's
saying integrate(c/x^n,x) returns -c/(1-n)*x^(1-n) but he wants
-c/(n-1)/x^(n-1).
