[PATCH] t5319: don't trip over a user name with whitespace

[Johannes Sixt <j6t@kdbg.org>]

On my Windows system where the POSIX commands are provided by MSYS2,
I observe this output:

$ ls -l Makefile
-rw-r--r-- 1 Johannes Sixt 197121 101780 Jun 30 09:33 Makefile

Notice the blank in the user name. Obviously, extracting the size
of a file by counting columns won't work. But two tests in t5319
do that. Use the stat command to print just the file size.

Notice further that the group ID is presented numerically. The
actual output used in the tests is:

-r--r--r-- 1 Johannes Sixt 197121 2239 Jan  1 01:03 .git/objects/pack/pack-A-40289997979ee9f2d7198a5b4ac9fe14e27cbe4b.pack

In both tests, this group ID was passed as --batch-size, but actually
the first of the two tests does not fail.

Now I have to wonder: Why that? The test carefully attempts to extract
the smallest pack size to pass as --batch-size argument. But when it
passes some large number, the test still passes. Is this the intent?

That is, both a small and a large --batch-size satisfy 'does not alter
existing packs', but some medium sized --batch-size satisfy the next
test 'repack creates a new pack'. That is very curious.

Disclaimer: I've no clue about this multi-pack-index thing.
