Allow wiki pages with names like "branch/BRANCH", "checkin/HASH", and "tag/TAGNAME" to automatically link to displays of the corresponding branch, checkin, or tag. (check-in: 56023854 user: drh tags: trunk)

Do not allow edits to wiki pages associated with branches, checkins, or tags for users who do not also have checkin privileges. (Closed-Leaf check-in: 60e8a08f user: drh tags: describe-objects-using-wiki)
02:13
Change the /info page Overview section to have "Wiki:" links for wiki display, instead of "Edit Wiki:" links. Users who want to edit, can do the additional "Edit" click from the wiki page. Also have /info honor the nowiki query parameter. (check-in: f17a5198 user: drh tags: describe-objects-using-wiki)
