Because it is correct; otherwise, truncation may occur.

What do you mean by "all"? On a 32-bit system, there won't be
a change because sizeof(long)==sizeof(Py_ssize_t).

Actually, on a 64-bit system, there won't be a change in memory
usage, either, because me_hash is followed by me_key, and me_key
is 8-aligned. So there is currently 4 bytes of padding between
me_hash and me_key; with the patch, the padding is gone.
