Add test for large files on windows

Original test by Thomas.
Add the extra fsck to get diagnostics after the add.
Verify the pack at earliest opportunity
Slight confusion as to why index-pack vs verify-pack...
It's -v (verbose) not --verify
Specify an output file to index-pack, otherwise it clashes with
the existing index file.
Check that the sha1 matches the existing value;-)
