Consider warning user if convco commit is run without any staged files

[cafkafk]

Is your feature request related to a problem? Please describe.
It's very frustrating when I run convco commit, type all the fields, only to find that I didn't stage any files with git add.

Describe the solution you'd like
I would prefer if convco commit printed a warning to the screen, informing me that I haven't staged any files.

Describe alternatives you've considered
I've thought that it could be automated, but that would be hard to do in a way that everyone likes, and a lot more work than just a warning that solves the most frustrating part.

Additional context
I don't have any.

At the moment convco commit is indeed building up the commit message, and then executing the git cli.

You could use convco commit -- -a to add all files.

Quick solution could be that we run git add -N and git add -p before, such that you can add the changes that are needed.

I made PR #148 to add git add -N . and git add -p to be run before showing the wizard and running git commit ..

Awesome, can't wait for this to be merged!

#151 adds the options --intent-to-add and --patch. This will disable the behavior to automatically do it, but you will be able to use environment variables to override the defaults.
