Subject: maint: update all copyright year number ranges
X-Git-Tag: v9.2~97
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=01755d36e7389aef48f712193976205e7381115b;p=thirdparty%2Fcoreutils.git

maint: update all copyright year number ranges

Update to latest gnulib with new copyright year.
Run "make update-copyright" and then...

* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Manually update copyright year,
until we fully sync with gnulib at a later stage.
* tests/sample-test: Adjust to use the single most recent year.
