Comment 7 for bug 173051

This is now config()urable:

    # Set subject on Return.
    set ::config(chat,subject-on-return) 1

    # Set subject on FocusOut.
    set ::config(chat,subject-on-focusout) 0

    # Revoke subject on FocusOut.
    set ::config(chat,subject-focusout-revoke) 0

Whenever the user edits the subject line, using above settings, the new (if changed) subject is sent together with the next message, or it can be sent off directly by pressing Return.
