Merge branch 'mm/send-email-cc-cruft' into maint
 
In addition to "cc: <a@dd.re.ss> # cruft", "cc: a@dd.re.ss # cruft"
was taught to "git send-email" as a valid way to tell it that it
needs to also send a carbon copy to <a@dd.re.ss> in the trailer
section.

* mm/send-email-cc-cruft:
  send-email: don't use Mail::Address, even if available
  send-email: fix garbage removal after address
