Views for pages with slugs will always redirect to the canonical slug

[irskep]

This method requires maybe too much copypasta for hypothetical new endpoints. I also considered a couple other options which would make the call sites fail unless they do things correctly

(slugified_title, was_equal) = slugify_title(title)
if not was_equal:
    return redirect(...)

try:
    title = slugify_title(title)
except SlugMismatch as e:
    return redirect(...) # where SlugMismatch has the slug value

@with_slugified_url(key='title', make_url=lambda title: url_for('page.xxx', title=title'))
def view(title):
  # ...

...but these seemed like overkill.

Ideally this snippet would be applied to every route with <title> in the URL... but this was already a corner case of a purely cosmetic nature so this is certainly good enough for the time being.
