Subject: Locale tweakery.  Add test case for bug id 20000809.003 to op/misc,
X-Git-Tag: accepted/trunk/20130322.191538~33762
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dd8482fcac1d87406d052ae3262cc452d6d23e15;p=platform%2Fupstream%2Fperl.git

Locale tweakery.  Add test case for bug id 20000809.003 to op/misc,
create a "fast path" for locale name probing using "locale -a"
if available, squash finally hopefully the s?printf resetting
the numeric locale (since, IIUC perllocale, it never shouldn't).
