(I'm not sure if this group is the right place to report bugs, but I'm
afraid I'd forgot about the issue
before I find the right place ...)

sage: lim ( x*(sqrt(x^2)-sqrt(x))/sqrt(x^2 -x), x=oo)
0

(The right answer is +Infinity, of course.)

after small modifications, the limit is evaluated correctly, e.g.:

sage: lim ( x*(sqrt(x^2)-sqrt(x))/sqrt(x^2), x=oo)
+Infinity

sage: lim ( x*(sqrt(x^2+x)-sqrt(x^2))/sqrt(x^2), x=oo)
1/2


What's wrong?
I am using
| SAGE Version 3.1.1, Release Date: 2008-08-17                       |

Thanks,
Robert
