Run 'make update-copyright'. * lib/regexprops.c (copying): Update the year number manually. The format of the copyright year number range in Texinfo files is "YEAR1--YEAR2" now, i.e., with 2x '-'. * tests/sample-test: Adjust to use the single most recent year. * All other files: Update copyright years via the above make run.
