signoff argument doesn't work

Kingxukai

As I type `-s`, it wont add a signoff trailer to commit msg. As the test case: ``` bash git cc -s --dry-run newfile: test would run: `git commit --message newfile: test --signoff --no-signoff --no-edit` ``` which has both --signoff and --no-signoff arguments.

I tried with `-s`, it seems still not work yet.

Right, I still have to cut a release that includes the fix.

Finally got around to publishing to all locations except scoop, which failed due to an invalid token.
