Merge branch 'ab/send-email-transferencoding-fix'

Since "git send-email" learned to take 'auto' as the value for the
transfer-encoding, it by mistake stopped honoring the values given
to the configuration variables sendemail.transferencoding and/or
sendemail.<ident>.transferencoding.  This has been corrected to
(finally) redoing the order of setting the default, reading the
configuration and command line options.

* ab/send-email-transferencoding-fix:
send-email: fix regression in sendemail.identity parsing
send-email: document --no-[to|cc|bcc]
send-email: fix broken transferEncoding tests
send-email: remove cargo-culted multi-patch pattern in tests
send-email: do defaults -> config -> getopt in that order
send-email: rename the @bcclist variable for consistency
send-email: move the read_config() function above getopts
