Merge branch 'nz/send-email-headers-are-case-insensitive'

When user spells "cc:" in lowercase in the fake "header" in the
trailer part, send-email failed to pick up the addresses from
there. As e-mail headers field names are case insensitive, this
script should follow suit and treat "cc:" and "Cc:" the same way.

* nz/send-email-headers-are-case-insensitive:
git-send-email: treat field names as case-insensitively
