#942: Add new git_branch_0v_to_dash_v rule

* fix fuckup `branch 0v` by...

...deleting branch `0v` and running `git branch -v` as the user intended

* use quotes consistently

* provide new  solution implementation based on feedback on PR

* rename files to more accurately reflect their more generic contents

* update import statement to match new file name

* update command name in README.md

* separate out matching tests so the pattern is clear for those who add matches in the future
