The <a action=""> form is checking to see if the action specified
exists and is linkable. There's no good way to automatically read that
out of the manual routes, which is why that doesn't work. show_action
and friends add their actions to some internal Hobo arrays so they are
known.
Note that the action= attribute is a shortcut; you can always just use
href= and get plain HTML link behavior without magic.
