summary: fix odd code for allowing URI clone template to either be specified with {repo} or _{repoid} (Issue #336) Clarify that if the configured URI uses {repo}, then clone_uri_by_id must replace that with _{repoid}. Also, if the URI uses _{repoid}, it is _def_clone_uri that must be computed by replacing it with {node}.
