Today I put an initial set of Emacs 30 "snapshot" binaries for Windows
on GNU alpha.  In the process, I created a new folder for emacs-30[0].
At the moment, this folder is without the customary README.

I've attached a patch that suggests changes based on how I name the
snapshots, locally, when building them.  All of this is totally open
to discussion :)

Previously snapshot builds included a (rather nebulous) date, e.g.:
  emacs-30-YYYY-MM-DD-no-deps.zip.

Locally, my snapshots, instead of any date, include the git revision
short-code effective in the source tree where the build is taking
place, e.g.:
  emacs-30-28a9438169f-no-deps.zip

TIA for sharing your thoughts; I can easily rename files, including
those already posted if necessary.

Background:

The file admin/nt/dist-build/README-windows-binaries is usually placed
at the root of each new folder that will contain windows binaries, for
example the "emacs-30" folder for snapshot (and eventually pre-release)
builds from (as currently called) "master".

The attached patch updates this file to reflect a change in how I've
been naming snapshot binaries, locally.

Snapshot binaries are in-tree source builds, rather than being made
from a release --or prerelease-- tarball.
