Subject: regexp_unicode_prop.t: Add tests, refactor
X-Git-Tag: accepted/trunk/20130322.191538~5802
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=19c4061aa8fa454637e29db1afd668c3f66d3a01;p=platform%2Fupstream%2Fperl.git

regexp_unicode_prop.t: Add tests, refactor

Refactor so that can test /i or not.  Add tests for using the new feature to
have user-defined properties work differently under /i.
