Carlos Martín Nieto 5520efb72a Correct the signature output from the reflog
The function to convert signatures into erlang terms was returning ok
with the rest of the tuple which geef_sig expects. We do not want the
ok there, so let that function give us the four terms and decide what to
do in each case.

The signature functions still want to return with ok before it, but the
reflog wants them together with the other parameters.
