[PATCH v1 1/2] log -G: Ignore binary files

From

<590f2ca6b5323c17365a1645b5d10e9ab30623c4.1542833244.git.thomas.braun@virtuell-zuhause.de>
In-Reply-To
<cover.1542831544.git.thomas.braun@virtuell-zuhause.de>

The -G <regex> option of log looks for the differences whose patch text contains added/removed lines that match regex.

The concept of differences only makes sense for text files, therefore we need to ignore binary files when searching with -G <regex> as well.
