Updated Git, Coreutils and Emacs, new script to prepare tarballs
Until now, one had to follow the instructions from [1] to prepare a standard software tarball before merging with the low-level tarballs-software repository [2]. The script only worked for '.tar.gz' suffix and was only available as a comment on Savannah (in [1]). With this commit, the script has been imported into Maneage as 'reproduce/software/shell/tarball-prepare.sh' to simplify future software updates. It work with all supported '.tar.*' suffixes (of the upstream tarball repository) and will convert the tarballs to Maneage's standard format. Also, this script has a minimal argument parser and can skip the tarballs that are already unpacked, allowing faster tests. This script was used to update the versions of: Coreutiles 9.0 --> 9.1 Git 2.34 --> 2.36 Emacs 27.2 --> 28.1 The main motive behind this update was Git which announced a vulnerability issue [3] and suggested an update to the latest version as soon as possible. More detail is described in this github blog [4], but in summary, it was a security issue on multi-user systems that has been found and fixed by Git developers. Since Maneage is often installed on such shared systems, it was important to make this update. GNU Coreutils and GNU Emacs were also updated because they are also commonly used. The following improvements have also done with this commit: - .gitignore: ignore emacs auto-save files (that end with a '#') - README-hacking.md: In the checklist for updating the Maneage branch, the no-longer-necessary '--decorate' option of Git was removed from the command to check the general branch history.

+# The inputs are assumed to be formatted with 'NAME_VERSION', and only for

+# It will unpack the source in a certain empty directory with the
+# 'tmpunpack' suffix, and rename the top directory to the requested format
+# of NAME-VERSION also. So irrespective of the name of the top original
+# tarball directory, the resulting tarball's top directory will have a name
+# formatting of NAME-VERSION.
