[docs] [issue26899] struct.pack_into(), struct.unpack_from() don't document support for negative offsets

[Paul Sokolovsky]

New submission from Paul Sokolovsky:

See
https://docs.python.org/3/library/struct.html#struct.pack_into
https://docs.python.org/3/library/struct.html#struct.unpack_from

Actual source contains code like:

    if (offset < 0)
        offset += vbuf.len;

to allow specify offsets from the end of a buffer.
