There is a leap between the description of the status quo and your
conclusion. "we just have to" becomes valid only after explaining
that sanitize_address turns the address-looking string into valid
addresses (and we do not want to send to malformed addresses--but
that goes without saying).

I do not quote see the point of this final note. mailboxes with
'q'es in them are also in regular use, and singling out '+' does not
make much sense in the context of explaining this change.

OK. The additional recipient address

is a nice touch. We make sure that, with or without necessary
quoting in the original, we produce the correct result ;-).
Let's mark it for 'next' soonish, with proposed log message
rewritten somewhat.
Thanks.

git-send-email: use sanitized address when reading mbox body
Addresses that are mentioned on the trailers in the commit log
messages (e.g., "Reviewed-by") are added to the "Cc:" list by "git
send-email". These hand-written addresses, however, may be
malformed (e.g., having unquoted "." and other punctutation marks in
the display-name part) and can upset MTA.
The code does use the sanitize_address() helper on these
address-looking strings to turn them into valid addresses, but it is
used only to see if the address should be suppressed. The original
string taken from the message is added to the @cc list if the code
decides the address is not suppressed.
Because the addresses on trailer lines are hand-written and more
likely to contain malformed addresses, when adding to the @cc list,
use the result from sanitize_address, not the original. Note that
we do not modify the behaviour for addresses taken from the e-mail
headers, as they are more likely to be machine generated and
well-formed.
