[issue7578] Behavior of operations on a closed file object is not documented correctly

[Nick Coghlan]

Note that one of the reasons for the slightly wishy-washy phrasing in
the docs is to give other implementations a bit more freedom in the way
way they handle these error cases.

Agreed that the main reason is the one Antoine gave though - the
ValueError is looking at things from the point of view that the program
passed in a closed file object when an open one was needed.
