 Log Message:
 PR lib/60885 and PR lib/60886 - add test cases to demonstrate bugs
 
 The changes in this test (amongst others, including adding tests of
 the nb_NO.UTF-8 domain for PR bin/60496 which should already be fixed)
 should expose the problems in printf(3) and scanf(3) noted in the PRs.
 Note that we do not currently have tests for wscanf(3) which has a similar
 problem to PR lib/60885, and consequently remains untested.
 
 These new tests are currently expected to fail - but are not going to
 be marked as expected fails, I want to see them actually fail.
 
 Fixes for the issues already exist, and will be committed to the tree
 soon after test failures have been observed.  Similarly, a fix for the
 wscanf(3) issue will be made at the same time (the bug is glaringly obvious,
 and its fix is considerably simpler than that for scanf(3) - not that that
 one was difficult) without that one ever having been observed - unless
 the proverbial someone quickly implements a test case for that.
 
 None of this is intended to be pulled up to any already released version
 of NetBSD (apart from the 60496 fixes, which already have been), as no
 existing release has an installed locale which can trigger any of the other
 bugs.  The scanf issue (60585, incl wscanf - it is the same issue, just
 occurring in a different way) is a plausible one - a real locale could
 trigger it, but none of NetBSD's existing locales do.   The 60886 issue is
 bizarre, no real locale is ever going to trigger that one.
 
 In addition to the added tests for the bugs, and simply to torture the
 implementation in ways the tests had not done before, the tests have
 been upgraded to not stop upon the first failure - all failing sub-tests
 will be reported before each test case fails.
