Subject: [PATCH (GITK FIX)] gitk: Fix the "notflag: no such variable" error in --not processing.

From: Alexander Gavrilov <[email-masked]>
Date: Mon, 1 Dec 2008 20:25:25 +0300

Commit 2958228430b63f2e38c55519d1f98d8d6d9e23f3 fixed the
switch statement used in option processing, which made some of
the previously unreachable cases executable. This uncovered the
fact that the variable used in the handling of the --not option is not
initialized.

This patch initializes it. Note that actually it is also possible to
remove it completely, because currently nobody uses the value.
