Pádraig Brady 3067a9293a maint: update all copyright year number ranges
Run "make update-copyright" and then...

* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* tests/sample-test: Adjust to use the single most recent year.

# These tests are designed for a 'sort' implementation that uses a
# discriminator, i.e., a brief summary of a key that may have lost info,
# but whose ordering is consistent with that of the original key.
# The tests are useful even if 'sort' does not use this representation.
# Test lexicographic sorting.
# A long-enough string so that it overruns a small discriminator buffer size.

# Test numeric sorting.
# These tests are designed for an internal representation that ordinarily
# looks at the number plus two decimal digits, but if -h is
# used it looks at one decimal place plus a 4-bit SI prefix value.
# In both cases, there's an extra factor of 2 for the sign.
