Whilst using tinyurl is justifiable where the URL in question is likely
of ephemeral interest (and especially if it's huge), for a post like this
that could usefully be found by someone DejaGoogling years hence, it's
better to provide the real URL, no matter how convoluted that might be.

Remember that all these "make a short URL" services only work for a few
weeks, not in perpetuity. (Or perhaps you didn't know that?)

Besides, Peter's original URL is hardly overtaxing; it even fits on one
line:
