reply to is fine, but how do you know what my email client has (hint,
not a copy of 1.5 years of history sitting around in it at the

Anyway, not a big deal, just properly quote emails in the future, that's
good to get used to no matter what :)

Try reading the stable mailing list archives, again, you are asking
about a patch 1.5 years ago.  I can't remember information about patches
sent _yesterday_ given the quantity we go through...
