admin: automate one more part of the release process
This script automates the process of updating NEWS, performs the resulting final commit (thus with a consistent log message), and applies a signed tag (v$VERSION) to the result. * build-aux/do-release-commit-and-tag: New script. * README-release: Document it.

+Usage: $ME VERSION RELEASE_TYPE
+
+Run this script to perform the final pre-release NEWS update
+in which the date, release-type and version string are recorded.
+Commit that result with a log entry marking the release, and apply
+a signed tag. Run it from your project's the top-level directory.
+
+Requirements:
+- you use git for version-control
+- a NEWS file, with line 3 identical to this:
+* Noteworthy changes in release ?.? (????-??-??) [?]
+- a version-controlled .prev-version file
+
+Options:
+ --help print this help, then exit
+ --version print version number, then exit
+
+EXAMPLE:
+To update NEWS and tag the beta 8.1 release of coreutils, I would run this:
+
+ $ME 8.1 beta
+
+Report bugs and patches to <bug-gnulib@gnu.org>.
