[PATCHv4 1/6] Git.pm: allow command_close_bidi_pipe to be called as method

[Michal Nazarewicz <mpn@google.com>]

From: Michal Nazarewicz <mina86@mina86.com>

The documentation of command_close_bidi_pipe() claims that it can
be called as a method, but it does not check whether the first
argument is $self or not assuming the latter.  Using _maybe_self()
fixes this.
