[PATCH v4 13/17] read-tree: show progress by default

[Derrick Stolee via GitGitGadget]

From: Derrick Stolee <dsto...@microsoft.com>

The read-tree builtin has a --verbose option that signals to show
progress and other data while updating the index. Update this to
be on by default when stderr is a terminal window.

This will help tools like 'git sparse-checkout' to automatically
benefit from progress indicators when a user runs these commands.
