Subject: [PATCH 2/5] update_unicode.sh: set UNICODE_DIR only once

From: [email-masked]
Date: Fri, 19 Dec 2014 15:39:28 +0100

From: Beat Bolli <[email-masked]>

The value is the same on both uniset invocations, so "Don't Repeat
Yourself" applies.

Since we're in a subshell already, there's no need to unset UNICODE_DIR
at the end.
