Long ago we decided that aliasing over shipped commands was a baaaad
idea, as it might get a shell script into trouble when all of a
sudden the "-s" option is being given to every commit invocation.

But you can install a commit-msg hook (.git/hooks/commit-msg)
in any project you want to ensure a Signed-off-by line is in the
commit message for.  Its handed the COMMIT_EDITMSG file, which is
what the message will be generated from.  Looking at the code for
git-commit.sh its perfectly OK if the hook edits the file too.

Further the hook could be interactive, prompting the user "are
you sure you don't want to sign this commit?" or can be skipped by
handing --no-verify to commit.


I just learned about commit-msg hook the other day when I was reading
through git-commit.sh and noticed I didn't implement invoking that
particular hook in git-gui...
