Git.pm: allow command_close_bidi_pipe to be called as method

mina86 · gitster · commit 1bc760aeb784 · 2013-02-07T10:37:13.000-08:00
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.
