If links are enabled there will be an additinal "git" links next to
"summary log tree" _if_ the config has clone-prefix set or the
repository has clone_url set. In case the clone-prefix contains multiple
enties then only the first one will be considered.
The intention is to present the git:// link for a given repo early to the user.
