[PATCH] Fix t5303 (the test case for pack corruptions) on Windows

[Alex Riesen <raa.lkml@gmail.com>]

The perldiag(1) has following to say about this:

    "Can't do inplace edit without backup"

	(F) You're on a system such as MS-DOS that gets confused if
	you try reading from a deleted (but still opened) file. You
	have to say -i.bak, or some such.

Ouch, I have the svn tests disabled, so I couldn't notice.

FWIW, resending with the rest corrected.
