False strong guarantee in documentation

[Kazutoshi Satoda <k_satoda@…>]

For many functions inserting pointers into a pointer container, the documentation says that they provide strong exception-safety guarantee while they are actually not. Instead, they perform delete on the passed pointer if an exception is thrown.

I propose the wording like this; "When an exception is thrown, nothing happens except performing delete x."

Note that replacing it with "basic guarantee" is over relaxing. One should be able to assume the contents of the container are unchanged when an exception is thrown.
