Unlike

    git log -S'this
    and
    that
    line'

which finds commits that changes the number of occurrences of the
given lines in the blob (typically 1 to 0 or 0 to 1),

    git log -G'frotz'

internally runs "git log -U0", and finds commits that adds or
removes a line that matches the given pattern 'frotz'.
