ui-log: try to disambiguate ref names The 'h' querystring parameter in cgit is normally used to specify a branch (i.e. a ref below refs/heads/), but if a repository contains a tag with the same name as a branch the output from ui-log would use the tag as start-revision. This patch tries to fix the issue by checking if the specified ref is valid as a branch name; if so, the full refname is used in the call to setup_revisions().
