When there are a log of changes in the git step, topgrade might be "stack" in pager (e.g. less) until the user will manually exit it.
Using '--no-pager' flag allow all the changes to be printed to screen regardless of the amount of commits or the user's git configuration.
* Show what's new in Git repositories
* Check for pull changes using ORIG_HEAD
It seems that either `--rebase` or `--autostash` causes ORIG_HEAD not to change. We thought about it
further and decided that `--ff-only` is a safer option for git pull
While `//?/C:/Users/Someone/config-files` is a valid path, it's not very human friendly.
Such paths are returned from `BaseDirs`. This patch formats them in the traditional way.
