From 11695bd0d7d8efa32066c3adf25007a896661da9 Mon Sep 17 00:00:00 2001
From: Xavier Chantry <shiningxc@gmail.com>

Subject: repo-add cleanup.

* change ln -s to ln -sf in the Makefile to prevent a failure when the link
already exists.
* make test_repo_db_file simpler and more natural, move the complexity out
of it.
* remove one $cmd = repo-remove check that wasn't needed
