Hangs forever with older git version (1.8.5)

[benningm]

git-archive-all uses the git check-attr command with -z options which did behave different before this commit:

git/git@f7cd8c5

git-archive-all expects the new behaviour and waits forever in the read on line 373.

Both RHEL/Centos 6 and 7 still use version <= 1.8.3.

Thanks for reporting. Would you be able to help with testing?

Please check version from the issue-65 branch.
