git: add test showing `hg commit -i` working on a git repo
Shows `hg commit -i` working on a git repo via the `git`
extension. Adds working directory changes to files `alpha` and
`beta`, then selects only `alpha` changes and commits them.
As of now this would fail for a filename that
includes uppercase characters due to the lack of case folding
support in the extension.
