Try clicking the Edit link for http://ikiwiki.info/todo/Add_showdown_GUI_input__47__edit/
The link produces a query string that the edit CGI interprets to
mean edit.mdwn
in an Add showdown GUI input
subpage.
There's something there now, but only because I created it. When I first tried it, it came up blank. I tried several different ways of altering the escaping of the query string to get the real page to come up, but I never succeeded, so I just grabbed the original text from git and pasted it into the new page....
So somehow the generation of Edit links and the CGI for doing the editing need to get in agreement on just how they're going to escape slashes in a page title.
