Added fn for Telescope to search intelligently.
Added fn for Telescope to search intelligently.

I kept running into the problem of, for instance, using `set autochdir`
(or opening a non-root file specifically) and having Telescope's default
`find_files()` only find additional files relative to that file/buffer
(versus across the entire Git repo).

This small little utility fn wraps the keybinding to intelligently use
`git_files()` when able, with a fallback to `find_files()` if our
file/buf isn't part of a Git repo.
