Subject: git-gui: fix use of undeclared variable diff_empty_count
X-Git-Tag: v1.6.3-rc4~1^2~3^2~1
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=8052e788b5e9ae2e2d06b5050fa73394ffe0993a;p=git.git

git-gui: fix use of undeclared variable diff_empty_count

Commit 584fa9cc introduced the global variable diff_empty_count, which
is used in diff.tcl. This variable wasn't declared anywhere which
resulted in an ugly error message box instead of the intended
informative message.
