[PATCH] ui-repolist: return HTTP 404 if no repositories found

[Peter Colberg]

Dear cgit maintainers,

With the following patch, cgit returns HTTP 404 Not found when querying
a non-existent repository. This is useful to signal to search engines
that a repository no longer exists. Further, webservers such as nginx
permit logging requests to different files depending on the HTTP code.

cgit_print_repolist() does an early return with an error page if no
repository is found. I added a helper function is_visible() to avoid
repeating the repo conditions (and risking them getting out of sync).

Regards,
Peter
