[PATCH v2 0/1] enhance "git restore --worktree --staged" behavior

[Eric Sunshine <sunshine@sunshineco.com>]

This is a re-roll of [1] which enhances git-restore to default --source
to HEAD when --worktree and --staged are combined.

Changes since v1:

* tighten the commit message and documentation changes as requested by
  Junio[2]

* drop patch 1/2 since 2/2 threw away all the changes from 1/2, and the
  end result is the same with or without 1/2

Although the code is identical between v1 and v2, I didn't include
Taylor's "Reviewed-by:"[3,4] since the documentation changes have been
refined a bit.
