[pacman-dev] [PATCH 9/9] repo-add: allow specifying symlink as repo file

[Dave Reisner]

If the repo file already exists, we allow specifying the symlink instead
of the tarball itself.

I'm fairly sure this is a safe use of readlink, since it doesn't involve any of
the flags for canonicalizing paths. I was able to test it on OSX with great
success.
