Introduction of --no-commit to "git commit" is absolutely necessary for
interactive users if we were to introduce commit.signoff, but I am not
sure about this change and similar ones given to the other Porcelain
commands that use "git commit".  They actually started making me think
that commmit.signoff might be more trouble than it is worth.

It is plausible that your workflow is to have others push to your 'mob'
branch and integrating good bits from there by cherry-picking, sort of
like using the 'mob' branch as if they are e-mailed patches.  In such a
setup, if you are so forgetful to type "-s" for your commit that you would
want commit.signoff configuration, you would likely to be equally
forgetful to type "-s" for your cherry-pick, and would want to have some
configuration affect how this part of the code works.

I however moderately doubt if the complexity and flexibility of having
rebase.signoff, revert.signoff, and cherry-pick.signoff as independent
options is worth it.  I am inclined to think that is too many knobs to
tweak, and it is far simpler to understand and easier to explain if the
single configuration, commit.signoff, applied to every Porcelain that
creates commits.

If we were to go that route, instead of passing --no-signoff when they
invoke "git commit", these commands need to take their own --no-signoff
option instead, and when neither --signoff nor --no-signoff is given, they
just should just invoke "git commit" and let it use the config (if set).
