Subject: [PATCH v3 1/4] difftool: silence uninitialized variable warning
Date: Wed, 20 Feb 2013 20:03:45 -0800 [thread overview]
Message-ID: <1361419428-22410-1-git-send-email-davvid@gmail.com> (raw)
Git::config() returns `undef` when given keys that do not exist.
Check that the $guitool value is defined to prevent a noisy
"Use of uninitialized variable $guitool in length" warning.
