			If a command is run with an absolute path as a pathspec inside a bare repository, e.g. "rev-list HEAD -- /home", the code tried to run strlen() on NULL, which is the result of get_git_work_tree(), and segfaulted. It should just fail instead. Currently the function returns NULL even inside .git/ in a repository with a work tree, but that is a separate issue.
