The "commit -s" on a merge commit lets you as the integrator to
attest that you made that merge.  The "mergetag" records the
signature by the contributor that says the tip that was merged was
what the contributor wanted to get merged.  

It is entirely reasonable to sign a merge commit that merges a
signed tag.  They serve two different and unrelated purposes.
