In Wiki pages, short-links created to local Wiki files were always expanded as regular Wiki Links. In particular, if a link wanted to point to a file that Gitea doesn't know how to render (e.g, a .zip file), a user following the link would be silently redirected to the Wiki's home page. This change makes short-links* in Wiki pages be expanded to raw wiki links, so these local wiki files may be accessed without manually accessing their URL. * only short-links ending in a file extension that isn't renderable are affected. Closes #27121. Signed-off-by: Rafael GirĂ£o <rafael.s.girao@tecnico.ulisboa.pt> Co-authored-by: silverwind <me@silverwind.io>
