guix-package: When rolling back to nothingness, point to the empty profile.
Suggested by Andreas Enge <andreas@enge.fr> at <http://lists.gnu.org/archive/html/bug-guix/2013-01/msg00316.html>. * guix-package.in (roll-back): Check whether PROFILE is valid using `file-exists?'. When NUMBER is zero, just emit a notice. When PREVIOUS-NUMBER is zero and PREVIOUS-PROFILE does not exist, build the empty profile, and link to it. * tests/guix-package.sh: Add tests. * doc/guix.texi (Invoking guix-package): Document the new behavior.
