Confused. Which part of this patch moves open inside a do{} block?
This was last touched by [9/18] but it doesn't do any such thing,
either.
Upon leaving this subroutine, $git filehandle will go out of scope,
so in that sense, close may not be necessary, but that does not
match what the proposed log message claims what the patch does.
Also, this patch does not remove "or die" 9/18 added, even though
the proposed log message claims that with autodie it is no longer
necessary.
I am not convinced that using autodie globally, without vetting the
calls the original code make, is a good idea in the first place.
How does this change interact with existing calls to open, close,
etc. that check the return value from them, now these calls throw
exception and will not give a chance for the existing error handling
codepath to intervene?
