gbp export-orig for multiple source tarballs

[Eriberto Mota <eriberto@debian.org>]

Dear mentors,

The airport-utils[1] repository has several .orig.tar.gz files, all
they committed in upstream and pristine-tar branches.

When I run 'gbp export-orig', I got several error messages[2]. So, is
clear for me that it is not the way to export all tarballs. Whats is
the right way?

Thanks in advance.
