A funny thing happened on the way to the button...

(…with apologies to Steven Sondheim)

While poking around, deciding how best to update the various helpers
involved in building the show-user-record page so that the *owner* of
said record can edit his profile, I was distracted by the fact that
Issue #69 is still open (and will remain so for some time, apparently).
More to the point, fixing `UsersHelper#profile_bio_row` and thus
replacing lines 9-11 of the current `show` template is stymied by
Rails' "helper"'s unhelpful escaping of markup concatenated as a
string.

I did, however, manage to get  the "member can view own profile page
spec" to prove that we're seeing the (HTML) markup we expect, rather
than just the untagged text. Once I quit futzing around with Rails'
`assert_select` and just used Nokogiri.
