Summary: Max and min are incorrect with one argument

Initial Comment:
max(1)

raises 'TypeError: iteration over non-sequence',

when it should simply return 1



Min has the same problem.



If there is one person in a room, and you ask for the

tallest person, there is a well-defined answer.

The tallest person is the only person.

So is the shortest person.



I ran across this when I was doing

apply(max, list) / apply(min, list)

to find out the ratio of maximum to minimum entries

in a list.    With a single-element list, I expected

it to return 1, instead of raising an exception.
