dovecot - May 2010 - !include

dovecot 1.2.11

Hello,

i do some tests with:

!include /etc/dovecot/conf.d/*.conf

dovecot fails to start if /etc/dovecot/conf.d/ is empty.
Is this a expected behaviour? 
!include_try works without error but seems to me to be more usual when explicit,
complete filename is given.
is a little bit strange in contrast to behaviour of other servertypes which
support a include-directive.

Thanks,
Andre
