git-send-email.perl: fold multiple entry "Cc:" and multiple single line "RCPT TO:"s
Some MTAs reject Cc: lines longer than 78 chars. Avoid this by using the same join as "To:" ",\n\t" so each subsequent Cc entry is on a new line. RCPT TO: should have a single entry per line. see: http://www.ietf.org/rfc/rfc2821.txt Signed-off-by: Joe Perches <[email protected]> Signed-off-by: Junio C Hamano <[email protected]>
