[Mailman-Developers] Subject's being mangled (I'm extendeding the length of this subject to see how it wraps)

[Tokio Kikuchi]

Hi,

I've uploaded a patch for pythonlib/email/Header.py

patching in the install dir would be OK because the installer
doesn't seem to overwrite it in the next make install of mailman.
