  1. add is_dot_or_dotdot inline function

    aspotashev committed with gitster Jan 10, 2009
    A new inline function is_dot_or_dotdot is used to check if the
    directory name is either "." or "..". It returns a non-zero value if
    the given string is "." or "..". It's applicable to a lot of Git
    source code.
