Another fast-import/import-tars issue

["Chris Riddoch" <riddochc@gmail.com>]

Hi, folks.

I believe I've uncovered an issue in fast-import, but I don't know the
code well enough yet to debug it.  So, I'll produce my evidence and
let others work on finding the solution.  It should be pretty easy to
reproduce.

First, I'm running: 1.5.2.rc1.9.g6644

Grab the tarball of Perl 5.8.8 - http://www.perl.com/CPAN/src/perl-5.8.8.tar.bz2

Note its md5, just so you know it's not corrupted from the outset.
b8c118d4360846829beb30b02a6b91a7  perl-5.8.8.tar.gz
a377c0c67ab43fd96eeec29ce19e8382  perl-5.8.8.tar.bz2

Try this:

$ tar -xjf perl-5.8.8.tar.bz2
$ cd perl-5.8.8
$ git init
$ git add .
$ git commit -a -m "Import from working tree copy"

Now, for convenience of debugging, I have myself a script I call
~/bin/fast-import-filter.sh:

#!/bin/bash
tee fast-import.log | git fast-import --quiet

Then, I have a slightly-changed ~/bin/import-tars script, like so:

20c20,21
< open(FI, '|-', 'git', 'fast-import', '--quiet')
---
> #open(FI, '|-', 'git', 'fast-import', '--quiet')
> open(FI, '|-', 'fast-import-filter.sh')

Now,

$ import-tars.pl ../perl-5.8.8.tar.bz2

Okay, so the trees pointed to by the tips of the master and
import-tars branches *should* be identical here, right?

$ git diff-tree master: import-tars: | wc -l
229

Not so good.
