Rather than reading it dynamically from the ChangeLog -- that,
remember, is only a dummy in a Git checkout! To avoid risking
the definition to get out-of-sync, let's enhance the maintainer
target 'update-copyright' to update it automatically (the same
way it's done in the Automake build system).
* configure.ac (RELEASE_YEAR): New AC_SUBST'd variable.
* cfg.mk (update-release-year): New maintainer-specific target
to automatically update the value of that variable.
(update-copyright): Depend on the new target.
* bin/local.mk (RELEASE_YEAR): Drop definition.
(edit): Simplify quoting of $(RELEASE_YEAR).

According to Automake's NEWS file, it is since at least Automake 1.8,
and in autoreconf we are already assuming aclocal >= 1.8 anyway.
* bin/autoreconf.in (parse_args): Simplify a little by just assuming
the automake option '--force-missing' is supported.
($automake_supports_force_missing): Delete, no longer needed.
* NEWS: Update.

* bin/autoreconf.in (run_aclocal): After the previous commit, this has
become just a useless wrapper around xsystem("$aclocal .."), so get rid
of it, and inline its expansion in the two places where it was used ...
(autoreconf_current_directory): ... in here.
Signed-off-by: Stefano Lattarini <stefano.lattarini@gmail.com>
The minimal automake and aclocal version required by the "most"
conservative important real world-projects (like Gnulib and Libvirt)
is 1.9 anyway (which is the version installed on old but still
supported installations of stable Distros like RHEL 5), so this
change should be safe and justified by now.
* bin/autoreconf.in (parse_args): Simplify by just assuming the aclocal
options '--force' and '--no-force' are supported and works correctly.
($aclocal_supports_force): Delete, no longer needed.
(run_aclocal): Heavily simplify by assuming that aclocal properly creates
'aclocal.m4' as lazily as possible.
