Subject: [PATCH] setup_git_directory(): fix move to worktree toplevel directory

From: Nguyễn Thái Ngọc Duy <[email-masked]>

When setup_git_directory() returns successfully, it is supposed to move
current working directory to worktree toplevel directory.

However, the code recomputing prefix inside setup_git_directory() has
to move cwd back to original working directory, in order to get new
prefix.  After that, it should move cwd back to worktree toplevel
directory as expected.

 This is a revised version of "Preserve cwd in setup_git_directory()"
 I sent before. Hopefully this time the commit message makes it clear.
