eldoc-diffstat — Make VCS diffstat available via eldoc

This package provides a way to display VCS diffstat information via eldoc. It supports Git and Mercurial repositories.

To turn on diffstat output in all supported major modes, enable global-eldoc-diffstat-mode. You can instead also enable eldoc-diffstat-mode in individual buffers or via mode hooks.
