[Dovecot] LIST command claims children exist in empty folder

Dovecot 1.2 (8834:5284f45c249a)

Should list return \HasChildren if no folders exist under it? I'm
using mbox format.

2 create testfolder/ 2 OK Create completed. 3 list "testfolder/" *

• LIST (\Noselect \HasChildren) "/" "testfolder/" 3 OK List completed. 4 list "testfolder/" %
• LIST (\Noselect \HasChildren) "/" "testfolder/" 4 OK List completed. 5 list "testfolder" %
• LIST (\Noselect \HasChildren) "/" "testfolder" 5 OK List completed. 6 list "testfolder" *
• LIST (\Noselect \HasChildren) "/" "testfolder"

Thanks, Jonathan
