Linking to non-existant wiki page is broken
Its impossible to easily link to a non-existant wiki page, then follow that link and create it, as it usually works for wikis. Lets say we define a link in Creole syntax:
This will create a link to: wiki/My_Page, but such page will report 404. Another problem is that when I try to create this page manually (Create link from wiki) and use title "My Page" it gets converted to "My%20Page" so its encoded differently than underscore used by Creole linking.
These two things make it really hard to quickly create pages on wiki, unless I'm doing something wrong.
