Subject: [PATCH] view: do not redundantly obfuscate addresses

We shouldn't rerun the address obfuscator on data we've
already run through.  Instead, run through the unescaped
text part and substitute the UTF-8 "\x{2022}" substitution
before it hits HTML escaping

Fixes: 9bdd81dc16ba6511 ("view: msg_iter calls add_body_text directly")
