Comment 7 for bug 266375

Originator: NO

This is derived from the python email module behavior that try to keep a
header line within 78 characters. Mailman parses the message first and do
something like adding subject prefix or message body header/footer then
regenerate RFC-2822 message. Email module thinks your subject has two part
structure separated by a comma and split by CRLF. I am not very sure but
current version of email doesn't distinguish structured and unstructured
headers defined in 2.2.1 and 2.2.2 of RFC-2822. Anyway, It is safer to
shorten the header lines within 78 charcters.

FYI, email module generates your subject header like this:
Subject:
=?utf-8?q?=5BMTD=5D_NAND=3A_CAF=C3=89_NAND_driver_cleanup=2C_fix?=
 =?utf-8?q?_ECC_on_reading_empty_flash?=
