Merge branch 'mm/send-email-cc-cruft-after-address'

"git send-email" attempts to pick up valid e-mails from the
trailers, but people in real world write non-addresses there, like
"Cc: Stable <redacted> # 4.8+", which broke the output depending
on the availability and vintage of Mail::Address perl module.
