Show branch:file that is being operated on. I had to make ActionItem a type and not a type class because withKeyOptions' passed two different types of values when using the type class, and I could not get the type checker to accept that.

{- git FilePath library
|
|
-
|
|
- Different git commands use different types of FilePaths to refer to
|
|
- files in the repository. Some commands use paths relative to the
|
|
- top of the repository even when run in a subdirectory. Adding some
|
|
- types helps keep that straight.
