/*
 * The repository summary page and the about page. The summary stacks the
 * branch list, the tag list and the head of the log into one table and ends
 * with the clone urls, reusing the listings ui-refs.c and ui-log.c draw
 * elsewhere. The about page renders the readme that config parsing picked for
 * the repository, either through the configured about filter or escaped as
 * plain text.
