[PATCH] Add missing inside_work_tree setting in setup_git_directory_gently

Without this, work_tree handling code in setup_git_directory
will be activated. If you stay in root work tree (no prefix),
it does not harm. It does if you work from a subdirectory though.

 Turns out my patch on NEED_WORK_TREE is fixing a wrong place.
