--commandfile not being respected in 3.0 beta

[anewhouse]

With the latest 3.0 beta installed, specifying a command file as an argument doesn't seem to be working. Running /Library/Application\ Support/Dialog/Dialog.app/Contents/MacOS/dialogcli --commandfile /var/tmp/dialogTest.log causes both dialogTest.log and dialog.log to be created in /var/tmp, and after that only updates to dialog.log are being processed
