Subject: test-lib: provide UTF8 behaviour as a prerequisite
X-Git-Tag: v1.7.12.1~25^2~1
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=5b0b5dd49b55e474a2df502902682853e2cd6e9d;p=git-core%2Fgit.git

test-lib: provide UTF8 behaviour as a prerequisite

UTF8 behaviour of the filesystem (conversion from nfd to nfc)  plays a
role in several tests and is tested in several tests. Therefore, move
the test from t0050 into the test lib and use the prerequisite in t0050.
