No warning before deleting non adjacent messages

[pilap82]

Hello,
i noticed that when you select many messages that are non adjacent and try to delete them, you have no warning (do you want to delete selected messages).
When you do the same with many adjacent messages, you have the warning.

by the way, if it is not clear, non adjacent means for example: select messages 1, 3 and 7 (with the Ctrl key).
adjacent would be to select messages 2, 3 and 4.

i'm using SVN 541.

bye
