wiki edit P --title New failed with "supply --body": renaming now keeps
the page's content, and edit needs one of --title, --body, --body-file
or --editor. wiki list --limit 1 returned every page because Gitea
replaces a limit of 1 with its default; the page list is now read whole
and paged on the client, so --limit and --page hold and the context line
counts the pages.
wiki create takes the title as an argument and, without --body, asks for
the content in the editor or an inline multi-line field. wiki view shows
the author, last update and revision count above the rendered page, and
--web opens it. wiki list and revisions show headed columns, page names
complete with Tab, and every change reports a ✓ line.
