update-copyright: avoid copyright notice date corruption
Given a sequence of copyright year numbers in which the final
one was a two-digit number that happened to be a substring of
a preceding four-digit year number, we would mistakenly update
the substring (from two- to four-digit) rather than the two-digit
number at the end, which, combined with the addition of the current
4-digit year number would yield two 5-digit year numbers, e.g.,
here, it would convert the first "99" to "1999, 2013" rather than
the final one:
1991, 99
11999, 20131, 1999
* build-aux/update-copyright: Tighten a regexp.
* tests/test-update-copyright.sh: Add a test case to trigger the bug.
