archiving rules regex issue ( Subject starts with )

[Robert Chavers]

I setup a archiving rule for "subject starts with 'Logwatch for'" using the following regexp:

^Logwatch for

However, piler is not working as expected. If the subject exactly starts with the above, it does not work. If I remove the carat ( ^ ) character, it does work correctly.

Your subject line may start as: "Subject: the actual subject" (notice the space after "Subject:").

Please find the attached diff that fixes this issue. I'll commit this to the source tree soon.
