[PATCH 0/7] nd/setup fixups

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

This replaces the last three patches in nd/setup in pu (from clean up
setup_discovered_git_dir to t1020-subdirectory)

Changes are:

 - Retain old behavior of setup_discovered_git_dir() when .git is not
   explicitly set by set_git_dir(), but later on by setup_git_env().
   This helps remove the ugly workaround in set_git_dir() earlier.

 - Include t0001 tests from Jonathan. You'll see I sneak more patches
   in from my old nd/setup from time to time, until I push all of them :)

 - set_git_work_tree() now allows multiple calls as long as the new
   worktree and the old one is the same, as Junio suggested.

 - Document update. Turns out not much is needed.
