I overlooked the GPG prerequisite when I created the "setup signed
branch" test in patch 1/3. I will send a patch to  rectify it ones
everyone agree with the idea behind this patch.

In patch 2/3 and 3/3, there are many tests which requires a branch
similar to that of "signed" branch, i.e. a branch with a commit having
GPG signature. So previously in v2, I created two new branches,
"test_sign" and "no_sign", which are identical to that of "signed"
branch. And with these branches, I wrote the tests in patch 2/3
and 3/3.

As suggested by Eric [1], rather than creating new branches, I
can take advantage of "signed" branch which already exists.
So, I created a new test to separate the creation of "signed" branch
from existing test "log --graph --show-signature". This was done
because I do not want new tests to depend on this test. If in future
someone changes this test then it will affect new tests introduced
in 2/3 and 3/3.

Now the new tests and existing one ("log --graph ... ") are using a
single branch "signed" to do there work.

If changing an existing test is not well justified here, then I can create
setup test for new tests only, without affecting the existing test.
