Dear SAGE developers,

On the other hand, we do get a correct result this way:

   ┌────────────────────────────────────────────────────────────────────┐
   │ SageMath Version 7.1, Release Date: 2016-03-20                     │
   │ Type "notebook()" for the browser-based notebook interface.        │
   │ Type "help()" for help.                                            │
   └────────────────────────────────────────────────────────────────────┘
   sage: import sympy
   sage: sympy.limit((x^(1/x)-1)*sqrt(x), x, infinity)
   0
   sage: sympy.limit(((1/x)^x-1)/sqrt(x), x, 0, '+')
   0

(If nothing else, users can be appropriately skeptical if Maxima and
SymPy are giving different answers.)

Sincerely,
Greg Marks
