RELEASING: Remove a meaningless step from the release process.

RELEASING: Remove a meaningless step from the release process.

The entire "make sure the code you want is in place" thing is part of
a larger release process that we don't document here at all. Instead,
we just focus here on the mechanics of pushing things out once the
larger process has determined the code is ready.

And the fewer steps there are, the better, (for making the
release-process as painless as possible and for avoiding any
mistakes).
